The U.S. Department of Defense requires CompTIA A+ for all IT personnel at IAT Level I under DoD 8570/8140. That single federal mandate — combined with roughly 75,000 open helpdesk and desktop support roles posted on any given week — has made CompTIA the most searched entry-level certification online. It has also spawned a training market with extreme quality variance: a $15 Udemy bundle and a $3,000 boot camp can cover identical exam objectives, and the difference often comes down to your study style, not the price tag.
This guide covers what online CompTIA courses actually include, which certification path makes sense for your goals, and what to realistically expect before you sit the exam.
Which CompTIA Certification to Study Online First
CompTIA has a logical certification sequence, and skipping rungs costs most people months of wasted study time. Here is how the core path breaks down.
CompTIA A+: The Default Entry Point
If you have no IT experience, A+ is the right first cert. The current exam series (220-1101 and 220-1102) covers hardware troubleshooting, operating systems (Windows, macOS, Linux, Android, iOS), basic networking, security fundamentals, and operational procedures. Most employers list it as the minimum qualification for helpdesk and desktop support roles that pay $40,000–$55,000 at entry level.
Typical online study time is 3–5 months at one hour per day. Each exam costs $253 through Pearson VUE; budget $550–$650 all-in with practice tests and a retake buffer.
CompTIA Network+: For Networking-Focused Roles
Network+ (N10-009) targets network administrator, NOC technician, and IT generalist roles that earn $65,000–$75,000. A+ is not a formal prerequisite, but the domain overlap makes sequencing them natural. Online courses typically run 40–60 hours of video content. CompTIA recommends nine to twelve months of networking experience before sitting the exam — that recommendation exists because candidates without hands-on context tend to fail performance-based questions.
CompTIA Security+: The Biggest Salary Accelerant
Security+ (SY0-701) is where the salary curve steepens sharply. Certified professionals report median compensation of $85,000–$100,000, and the cert satisfies DoD 8570 IAT Level II, which opens federal contractor and government IT positions that are largely inaccessible without it. Most candidates study 2–4 months online after already holding A+ or Network+.
Specialist Certs Beyond the Core Three
CompTIA also offers CySA+ (analyst-level security), PenTest+ (offensive security), CASP+ (advanced security architecture), Cloud+, Linux+, and DataSys+. These are worth pursuing after the core three. Several online course providers sell bundle subscriptions that include all of them — worth considering if you have a clear multi-year roadmap.
What Online CompTIA Courses Actually Include
The exam objectives are public documents. CompTIA posts them free on their website, and every legitimate course is built directly from them. What varies between online CompTIA courses is delivery format, lab depth, and how current the content is.
Video Lecture Courses
The majority of online CompTIA training is video-based: an instructor walks through exam domains on screen, typically with slides and occasional system demos. Course lengths range from 20 hours (bare-minimum domain coverage) to 60+ hours (comprehensive with worked examples). Professor Messer's free A+ course sets the baseline for this format — if a paid course isn't noticeably better, it isn't worth buying. Udemy, LinkedIn Learning, and Pluralsight all have competitive paid options that layer in quizzes and section reviews.
Lab-Based Platforms
Platforms like CompTIA CertMaster Labs and Dion Training include virtual machine environments where you actually configure systems, troubleshoot networks, or analyze security events rather than just watching someone else do it. Labs matter specifically for performance-based questions (PBQs) — simulations that appear at the start of every CompTIA exam. Candidates who skip hands-on practice routinely report that PBQs were what failed them, not the multiple-choice section.
Practice Exam Banks
Regardless of which course you take, add a dedicated practice exam bank. MeasureUp (CompTIA's official partner), Dion Training, and ExamCompass all offer question banks that mirror the real exam format and difficulty. The standard benchmark: score 85–90% consistently on practice sets before booking your actual exam date. Anything lower and you're statistically likely to need a retake.
How to Evaluate an Online CompTIA Course Before Buying
These are the specific signals that separate useful online CompTIA courses from filler content:
- Exam version currency: CompTIA retires exam versions on a schedule. A+ 220-1001/1002 was retired in October 2023. Verify any course you're considering targets 220-1101/1102. For Security+, confirm SY0-701, not the retired SY0-601.
- Instructor credentials: Look for instructors with active CompTIA certifications and verifiable real-world IT history. Teaching a cert you passed a decade ago without current field experience shows in the examples used and the depth of troubleshooting scenarios.
- Lab inclusion: If the course has no hands-on labs or virtual environments, you're getting lecture-only prep. That covers memorization but leaves you exposed on PBQs.
- Update recency: Check the "last updated" date on any course listing. Content older than 18 months may have stale coverage, particularly in the security and cloud domains where CompTIA refreshes objectives more aggressively.
- Practice question volume: A minimum of 150–200 quality practice questions per exam is table stakes. Less than that and you're not seeing enough question variation to be ready.
- Pass guarantees and voucher bundles: Some instructors and platforms bundle the exam voucher with a retake guarantee. These are worth the premium if you're self-funding and have a hard deadline.
Top Online Courses to Consider
The following courses are available on major platforms and cover skills directly relevant to IT support and certification study. Ratings reflect verified learner scores.

If you're planning to deliver end-user training, create internal IT documentation, or build your own CompTIA prep content, it covers how to structure and deliver effective online instruction.
Satisfaction Guaranteed: Develop Customer Loyalty Online
Helpdesk and IT support roles are as much customer-facing as technical. This Coursera course (rated 9.7) covers communication strategies, expectation management, and loyalty-building — skills that determine whether an A+-certified technician advances into senior support or stays on tier-one tickets indefinitely.
FAQ
How long do online CompTIA courses take to complete?
Most online CompTIA A+ courses run 40–60 hours of video content. Add practice exam time and you're typically looking at 80–120 hours of total study per exam. At one hour per day, that's 3–4 months per exam. Candidates with prior IT experience often cut that in half. Network+ and Security+ have similar study timelines, though Security+ demands deeper conceptual understanding and tends to take longer for candidates without security job experience.
Are online CompTIA courses enough, or do I need in-person training?
Online CompTIA courses are sufficient for most candidates. CompTIA exams test knowledge and applied reasoning — the labs you get from virtual environments in quality online courses are comparable to what in-person boot camps provide, and often more flexible. In-person training adds accountability and cohort learning, but the pass rates between online-only and in-person candidates are not significantly different when the online course includes proper lab simulations.
What is the cheapest way to get CompTIA certified online?
Professor Messer offers free A+, Network+, and Security+ courses on his website — the only cost is the exam vouchers ($253 each). Supplement with ExamCompass (free practice questions) and you can realistically prepare for under $600 total per certification. Udemy courses from instructors like Jason Dion routinely go on sale for $15–$20 and are a solid paid alternative if you want structured video plus practice exams bundled together.
Do online CompTIA courses expire or go out of date?
CompTIA certifications themselves expire every three years and require renewal through continuing education (CE) credits or retaking the exam. Online courses do not expire, but they can become outdated when CompTIA releases new exam versions. Always verify a course targets the current exam objectives before purchasing — the "last updated" date on course listings is the most reliable signal.
Is CompTIA A+ worth it if I already have a degree in IT?
It depends on the role. Many employers treat A+ as a screening filter for helpdesk and tier-one support positions regardless of degree. For mid-level or specialized roles, Network+ or Security+ carries more weight than A+. If you have a CS or IT degree and are targeting roles above entry-level helpdesk, Security+ is usually the more strategically valuable cert to pursue first.
Can I take CompTIA exams online at home?
Yes. CompTIA offers online proctored testing through Pearson VUE OnVUE. You take the exam at home with a webcam and a proctor monitoring remotely. Requirements include a quiet private room, a reliable internet connection, and a system that passes the OnVUE readiness check. The exam experience and content are identical to a physical testing center.
Bottom Line
Online CompTIA courses are a legitimate path to certification — the exam content is objective-driven, not experience-driven, and the best online courses include the labs and practice question banks you actually need. The main pitfalls are buying outdated content (check the exam version), skipping hands-on labs (PBQs will expose this), and underestimating practice exam requirements.
If you're starting from scratch: begin with A+ using a video course that includes labs (Dion Training, Professor Messer, or CompTIA CertMaster are the benchmarks), add a 200-question practice bank, and don't book the exam until you're consistently hitting 85%+. After A+, Security+ is the highest-return next step by salary and role access — the DoD compliance angle alone makes it worth prioritizing over Network+ for most career goals.
The certification isn't an endpoint. It's a filtering mechanism that gets your resume past automated screening. What you do with the first role it unlocks determines the rest of the trajectory.
