CompTIA A+: Exam, Cost, and Prep

Short answer: CompTIA A+ is a vendor-neutral, foundational IT support credential covering hardware, mobile devices, basic networking and cloud concepts, operating systems, security fundamentals, and operational procedures, commonly delivered as two separate exams with no required prerequisite. It is the credential family entry help desk and IT support postings name most often. Study hours and cost are both modest and illustrative; confirm both on CompTIA's own current pages before you commit.

Searches for CompTIA A+ mostly surface one of two kinds of page: a bootcamp’s landing page promising a pass in a weekend, or a forum thread arguing about an exact question count and pass score that was accurate the year someone posted it and may not be accurate now. Neither answers the actual question, which is what this specific certification covers, who actually needs it, what it costs and takes, and what passing it unlocks next.

This brief answers that directly. It explains what A+ certifies, the two-exam structure described by mechanism rather than a number that will go stale, the format you should expect, who should prioritize it and who should skip it, how to build a study plan, realistic cost and time, and what comes after you pass. It sits alongside our cybersecurity certifications for beginners brief, which places A+ against CompTIA Network+ and Security+, our how to get an entry-level IT job breakdown for the destination role, and our IT certification roadmap for sequencing.

What CompTIA A+ actually certifies

A+ sits at the broadest, most foundational tier of the IT certification market, which our cybersecurity certifications for beginners brief maps against CompTIA Network+ and Security+. Its job is deliberately wide: confirm that you can diagnose and repair common hardware problems, configure and support mobile devices, understand basic networking and cloud concepts well enough to connect and troubleshoot a device, install and maintain operating systems, resolve common software problems, apply foundational security practices, and follow documented operational procedures safely.

What it deliberately does not certify is deep specialization in any one of those areas. It is not a dedicated networking exam the way Network+ is, and it is not a dedicated security exam the way Security+ is. That is exactly why it is positioned as the entry credential for an IT career rather than the destination. Read CompTIA’s own description on its certification page for the current, authoritative framing of scope, since CompTIA periodically revises how it describes the exam.

Who this certification is actually built for

Three groups get real value from A+, and they overlap only partly with what a bootcamp’s marketing implies. The first is a genuine beginner who wants a recognized, hiring-relevant anchor before specializing, rather than relying only on self-taught tinkering that carries less weight in an applicant-tracking filter. The second is someone who has been informally fixing computers and phones for friends and family and wants a credential that formalizes that hands-on skill into something a resume filter recognizes. The third is someone whose employer or target postings name A+ explicitly as a requirement or a strong preference for a help desk or support role.

What it is a poor fit for is someone already holding documented, multi-year IT support experience and a more advanced, specialized credential, who is treating A+ as a necessary first rung when their experience has already cleared that bar. If you already have real troubleshooting experience and a more advanced credential, the honest move is usually to skip A+ and go straight to the credential your target roles actually ask for, which our cybersecurity certifications for beginners brief covers in its sequencing section.

The two-exam structure, explained by mechanism

CompTIA has commonly delivered A+ as two separate exams rather than one, and the exact exam codes, names, and content split have changed across past exam-guide revisions, so understanding what each exam is actually testing is more durable than memorizing a code CompTIA may update. In broad strokes, one exam has focused on the physical and device side of IT: hardware components and troubleshooting, mobile devices, basic networking hardware and concepts, and introductory cloud and virtualization ideas.

The other exam has focused on the software and operational side: operating system installation, configuration, and troubleshooting, software and application troubleshooting, foundational security practices and common threats, and operational procedures such as documentation, safety, and professional communication with end users. You generally need to pass both exams to earn the full certification, though the specific requirement, sequencing, and whether a single combined sitting exists at any given time is set by CompTIA and worth confirming directly in its current exam guide before you plan your study schedule around it.

Exam format: what to expect walking in

Each exam is delivered as a timed, proctored assessment, either at a test center or online with a remote proctor. Past versions of CompTIA exams, A+ included, have mixed multiple-choice and multiple-response questions with performance-based items that present a short, practical scenario and ask you to apply a skill rather than simply recognize a term. Some CompTIA exams also include items used only to evaluate future content, and you generally cannot tell which questions those are, so the practical approach is to treat every item as if it counts toward your score.

Rather than quoting a specific question count, time limit, or passing score here, since CompTIA has adjusted these details across past exam-guide revisions, download the current exam guide for both exams from CompTIA’s own certification page before you register and read it in full. It states the current format, timing, question types, and scoring approach directly from the source that controls them. Our walkthrough of an online proctored exam covers what the remote-proctoring experience itself involves if you choose that sitting option for either exam.

Prerequisites: what CompTIA requires and recommends

Formally, there is no required prerequisite for either exam. CompTIA does not require you to hold another certification or submit documented work history before registering for A+, which is a large part of why it functions as the very first anchor credential in IT. CompTIA has, in past exam guides, described A+ as appropriate for candidates with limited or no prior IT experience, more so than its higher-tier credentials like Network+ or Security+, which typically assume at least some foundational familiarity A+ itself provides.

Treat this as a spectrum rather than a binary gate. Someone with genuinely no computer hardware or operating system experience can pass both exams, but should plan for more study hours and lean more heavily on structured material and hands-on practice, since nearly everything will be new. Someone who has already built or upgraded their own computer, reinstalled an operating system, or troubleshot a phone or tablet problem will find a meaningful share of the practical material maps onto things they already know, which shortens the runway considerably.

Does CompTIA A+ require coding

No, and this is one of the more reliable, durable things to say about this certification. A+ does not ask you to write, read, or debug code in any programming language at any point, across either exam. It is a practical and applied certification about diagnosing hardware, configuring operating systems and mobile devices, applying basic networking and security concepts, and following documented procedures, not an exam about implementation in a specific language or framework.

This is precisely why A+ works well as an entry point for career changers who are not software developers. Someone changing careers from retail, hospitality, or an unrelated field entirely can study the hardware components, the operating system concepts, and the troubleshooting methodology without first needing to learn to code, which is a genuine and significant barrier in several of the more advanced technical certifications on this site. If your longer-term plan includes a hands-on, infrastructure-heavy specialization, expect scripting comfort to be built separately later, a point our how to become a cloud engineer brief covers for that path specifically.

The domains at a glance

The table below summarizes the broad areas A+ has commonly covered across its two exams, by what each one is broadly testing and who tends to find it most approachable, without quoting a specific percentage weighting that CompTIA periodically revises in its own exam guide.

Read this as a map of where your own study time is likely to go furthest rather than a scored breakdown, and confirm the current official domain names and weighting on CompTIA’s own exam guide before finalizing a study plan around it.

Illustrative study hours by starting background

The chart below shows illustrative study hours by starting background, covering both exams combined and scaled to the largest bar so you can see relative commitment at a glance. These are planning placeholders rather than measurements, and your own prior hands-on exposure to computer hardware and operating systems is the single biggest factor in where your own number lands.

The spread matters more than the exact hour counts. Someone already fixing computers informally or working an adjacent support role moves through this material noticeably faster than a complete beginner, because the hardware vocabulary and basic troubleshooting instincts are no longer new. Run your own background and weekly pace through the companion above to see your own estimated study window.

Illustrative study-time allocation across the two core exams

The chart below suggests how a newcomer might illustratively spread study time across the two exams, scaled to sum to 100. This is a planning suggestion based on the relative breadth of each exam’s subject matter, not CompTIA’s official scoring weighting, which is published separately in the current exam guides and should be the figure you plan the fine detail against.

The reason the hardware and device side gets the larger illustrative share is breadth, not difficulty. It touches more distinct physical components, connector types, and device categories, so there is simply more surface area to become familiar with before moving to the software and operational half, which tends to reward careful reading and hands-on configuration more than raw memorization of parts.

How to build a study plan around the two exams

The most reliable study plan treats the two exams as two separate, sequential pushes rather than one combined cram. Start with the hardware and devices exam, since it is the most hands-on and the easiest to reinforce with physical practice if you have access to any spare equipment. Move through mobile devices and basic networking next, since both build naturally on the hardware foundation.

Once you pass or feel ready on the first exam, move to the operating systems and software material, since it tends to be the largest single block on the second exam. Fold security fundamentals in alongside it, since the two overlap once you reach topics like malware removal and safe configuration. Save operational procedures for last, since it is typically the smallest section and the documentation and safety concepts click faster once you already understand the technical material they apply to. Our how to study for a certification exam brief covers building that habit into a weekly plan.

Hands-on practice and why it matters

A+ includes applied, scenario-style items in past exam versions alongside the multiple-choice and multiple-response questions, which makes pure slide-reading a weaker preparation strategy than it would be for a purely conceptual exam. Confirm the current question types in CompTIA’s exam guides, but plan for some hands-on practice regardless, since recognizing a component name in a photo is a different skill from diagnosing why it has failed.

If you have access to an old computer you no longer need, opening the case, identifying the components, and reseating a few of them teaches more in an hour than a much longer reading session. If you do not have spare hardware, a free or very low-cost virtual machine environment lets you practice operating system installation, configuration, and basic troubleshooting without needing physical equipment at all. Our how to build an IT home lab brief, written for hands-on exam prep generally, covers the setup in more depth, and even a few hours of hands-on exposure tends to outlast a much larger number of hours spent passively reading.

Practice exams and how to use them honestly

A good practice-exam set is one of the highest-value purchases in preparing for A+, and it is worth treating separately from a course subscription, with a separate set for each of the two exams. The honest way to use one is diagnostically: take a full practice exam reasonably early, before you feel ready, to find out which area is actually weak rather than which one you assume is weak. Then concentrate study time on the gap, not everything evenly, and retake a fresh set closer to your exam date to confirm the gap has actually closed.

The dishonest way to use practice exams is to memorize a small question bank until the scores look good, which produces false confidence and nothing more, since the real exam will not repeat those exact questions or phrasings. Favor a practice-exam provider that explains the correct answer and the reasoning behind it rather than just the result, since the explanation is where the real studying happens. Treat a suspiciously high score on a memorized bank with real skepticism rather than relief.

How to tell if you are actually ready to sit the exam

Readiness is easy to guess at and hard to measure honestly, so use a short checklist instead of a feeling, applied separately to each of the two exams. First, can you identify common hardware components and ports by sight and describe what each one connects or does. Second, can you walk through a basic operating system installation and the first few configuration steps you would check if a machine will not boot.

Third, has a recent full-length practice exam put you comfortably above the passing range you are targeting, taken under timed conditions with explanations you genuinely understood rather than guessed at. Fourth, have you spent real time on at least one hands-on task, reseating a component, installing an operating system in a virtual machine, or troubleshooting a real device problem, rather than only reading about these ideas. Fifth, do you understand basic security hygiene well enough to explain why a given practice is recommended, rather than having memorized a rule without the reasoning behind it. If all five are a genuine yes for a given exam, you are likely ready for it. If two or more are still a no, that is useful information about where your remaining hours should go, rather than a reason to delay booking a date, since the date itself is what keeps the remaining study focused.

How much the A+ exam costs

Exam fees are set and periodically revised by CompTIA, so treat every number here, including this one, as an illustrative placeholder rather than a live quote. A+ has commonly been delivered as two separate exams, each with its own fee, so budget two registrations rather than one, a pattern our how much do certifications cost brief covers across certifications generally.

Budget the two exam fees and your preparation materials as separate numbers. A reputable practice-exam set and official study guide can cover most people’s preparation for a modest combined outlay, while an instructor-led bootcamp adds considerably more cost without necessarily improving your odds if you are already a disciplined self-study candidate. Confirm the current exam fee for each exam directly on CompTIA’s own certification pricing page before you register, since that is the only source that will not be stale by the time you read it.

How to register and schedule the exam

Registration runs through CompTIA’s own certification portal and its testing partner, where you create an account, select the first exam, and choose between a test center or an online proctored sitting based on what is available near you and what you are comfortable with. Download and read the current exam guide for both exams before you book a date, since it states the authoritative format, timing, and scope you are planning against rather than relying on a secondhand summary.

Booking the date for your first exam before you feel fully ready is a genuinely useful tactic rather than a risk, because a date on the calendar converts a vague study intention into a weekly schedule with an endpoint, which is the single biggest predictor of someone actually finishing their preparation. If you choose the online proctored option, read what that experience involves beforehand in our walkthrough of an online proctored exam, since the setup and identity-check steps catch people off guard more often than the questions do.

What exam day actually looks like

For an in-person sitting, expect a standard test-center process: identity verification, a locker for personal items, and a proctored room with no notes or outside materials permitted. For an online proctored sitting, expect an identity check over webcam, a scan of your workspace to confirm it is clear, and a remote proctor monitoring the session, with specific technical and environment requirements that the testing partner publishes and that are worth reviewing the day before rather than the hour before.

Either way, the mechanics of the exam itself are broadly similar: a timed, scored assessment delivered on screen, with the ability to flag questions you are unsure of and return to them before submitting, within whatever time limit the current exam guide states. Arrive, or log in, with time to spare, since the identity and setup checks take longer than most people expect, and a rushed start adds unnecessary pressure to an exam that mixes recall with applied, performance-based items.

Common mistakes people make preparing for this exam

A handful of mistakes account for most of the wasted effort. The first is treating a video course as sufficient on its own, without supplementing it with practice exams and some hands-on time, which leaves gaps that only surface as surprise on exam day when a performance-based item expects applied troubleshooting rather than recall.

The second is memorizing a practice-question bank instead of understanding the reasoning, which produces a score on that specific bank that does not transfer to the real exam’s different phrasing of the same underlying ideas. The third is treating the two exams as one combined study project with no clear split, which tends to leave the second exam under-prepared once motivation fades after the first one is booked or passed. The fourth, specific to candidates who already tinker with their own devices, is underestimating the exam because the hardware material feels familiar, then being surprised by the breadth of operating systems, security, and procedural material on the second exam. The fifth is skipping the current exam guides entirely and studying from someone else’s out-of-date summary, which is an easy mistake to avoid by simply reading the source CompTIA publishes before you start.

Is CompTIA A+ worth it

Worth is a relationship between the credential and what you need it to do, not a property of the credential itself, so the honest test is to name the specific job before you study. If the job is clearing a resume filter or a job-posting requirement that names A+ directly, it does that reliably, since it is the credential family entry IT support postings name far more often than informal experience alone. If the job is building a defensible, broad IT foundation before specializing, it does that well, since the domain spread is deliberately wide rather than deep in any one direction.

What it is not worth doing is buying it as a substitute for a specialized, role-specific credential once your experience and target roles have already moved past the foundational tier. Our are certifications worth it brief runs this same test across the wider certification market, and the answer here follows the same logic: match the credential to the specific job you need it to do, not to its general reputation.

How A+ compares to CompTIA Network+ and other IT support options

Laid side by side, A+ and Network+ occupy different places in the same track rather than competing head to head, a comparison our cybersecurity certifications for beginners brief covers in more depth from the security angle. A+ is the broader, more foundational credential, covering hardware, mobile devices, operating systems, basic networking, and security together, and it formally assumes no prior experience. Network+ goes deeper into networking specifically, assuming the general IT literacy A+ already builds, and it is the more direct next step for anyone heading toward a networking or infrastructure specialization.

Some beginners also compare A+ against informal, self-taught experience alone, built from tinkering with personal devices with no credential attached. That experience is genuinely useful and worth describing in an interview, but applicant-tracking systems and recruiters screening general IT support applications tend to filter by naming a recognized credential far more often, and A+ is usually that credential for entry support roles. The practical sequence many beginners follow is building hands-on familiarity informally first, to confirm genuine interest at low cost, then A+ as the anchor credential once ready to commit to a proctored exam pair.

What comes after A+

The common next move is a credential chosen by the direction you want to specialize in rather than by which name sounds most advanced. Someone heading toward networking or infrastructure roles typically looks at CompTIA Network+ next, which builds directly on the basic networking concepts A+ introduces. Someone heading toward a security-focused role typically looks at CompTIA Security+ next, using A+ as the general foundation that makes security concepts easier to place in context, a path our CompTIA Security+ brief covers in full.

None of these formally require A+ first in every case, but the hardware, operating system, and troubleshooting vocabulary it builds makes the next tier noticeably easier to absorb, since you are no longer learning basic IT terminology at the same time as learning how to apply it in a specialized context. CompTIA periodically restructures its certification names and prerequisites, so confirm what currently exists and what each one requires directly on CompTIA’s own certification roadmap before committing to a specific next exam. Our how to get an entry-level IT job breakdown sequences the destination role in full, and our IT certification roadmap places A+ against the wider set of tracks on this site.

Renewal and keeping the credential current

CompTIA certifications, A+ included, run on a renewal cycle that CompTIA sets and publishes, historically satisfied through a continuing-education program, re-examination, or an equivalent recertification path before the credential expires. Renewal terms and the current cycle length are published and periodically revised on CompTIA’s own continuing-education page, which is the only reliable source to plan against rather than a number you may have seen quoted elsewhere.

The practical implication is to treat the credential as something you keep current rather than something you earn once and forget. Set a reminder well before the expiry date CompTIA’s own records show for your certification, and decide then whether to recertify at the same level or let the credential lapse because a more advanced credential has since superseded it on your resume. Our how long does the certification process take brief covers this earn-to-expiry cycle across certifications generally.

A worked example: a first-time study plan

Follow one illustrative candidate so the whole sequence is visible at once, with every figure a planning placeholder rather than a quote. Marcus has never worked in IT professionally, but he has built his own gaming computer and troubleshoots his family’s Wi-Fi when it breaks, which gives him real, if informal, hardware and networking exposure. He can commit an illustrative 7 hours a week. Based on that starting point, he budgets an illustrative 85 study hours across both exams rather than the higher figure a complete beginner would need.

He opens the current exam guides for both exams first and builds his plan around the hardware and devices material initially, since it overlaps most with what he already knows, then mobile devices and basic networking. He sets aside one weekend to open an old laptop and identify its components by hand rather than only reading about them, and he takes a full practice exam for the first exam after three weeks to confirm readiness before booking a date. Once that exam is passed, he shifts to operating systems, security fundamentals, and operational procedures for the second exam, using a fresh practice set to diagnose weak areas before his second booking.

At 7 hours a week, his illustrative 85 hours works out to roughly 12 weeks across both exams, and he budgets an illustrative 550 dollars for the two exam fees combined, replacing that placeholder with CompTIA’s current published fees before he pays. Change the starting input and the plan changes with it: a complete beginner following the same method would budget closer to the 120-hour end of the chart above and a longer runway. Run your own version of Marcus’s plan in the companion above and against our ROI calculator.

The bottom line

CompTIA A+ is a vendor-neutral, foundational IT credential spanning hardware, mobile devices, basic networking and cloud concepts, operating systems, security fundamentals, and operational procedures, commonly delivered as two separate exams with no coding and no formally required prerequisite. It is a genuinely useful anchor for a beginner who needs a recognized, hiring-relevant credential, for someone formalizing hands-on skills built informally, and for anyone whose target postings name it directly, and a weaker spend if your experience and target roles have already moved past the foundational tier.

Study time and cost are both modest relative to what comes next, and the honest way to plan either is against CompTIA’s own current exam guides and pricing page rather than a secondhand number. Build your study plan around the two exams in sequence, add hands-on practice rather than only reading, diagnose weak areas with a practice exam early for each one, and book a date before you feel fully ready. Price your own plan in our certification ROI calculator, sequence the step after it with our IT certification roadmap, and A+ becomes what it is meant to be: a recognized, broad anchor point rather than the whole climb.
