IT Certifications: What They Are and How to Choose the Right One
Updated
An IT certification is a credential issued by a vendor or standards body that verifies your knowledge of a specific technology, platform, or practice. It differs from an IT training course, which is the instruction you take to build skills, and from a bootcamp, which is an intensive, often broader program. You earn a certification by passing an exam; you complete a course by attending or finishing the material. The two are related but not interchangeable, and choosing well means matching the credential to a target role, checking its prerequisites and renewal rules, and picking a study path that fits your schedule.
Certifications vs. training courses vs. bootcamps
These three terms get used loosely, so it helps to separate them by what you actually walk away with.
| Format | What you get | Typical purpose |
|---|---|---|
| IT certification | A credential after passing an exam | Prove a defined skill level to employers |
| IT training course | Instruction and practice, sometimes exam prep | Build or refresh skills |
| Bootcamp | Intensive, multi-week skill program | Career change or rapid upskilling |
A training course can prepare you for a certification exam, but finishing the course does not make you certified. Conversely, some experienced professionals pass exams with self-study and no formal course. The right sequence for most people is: pick the certification, then pick the training that maps to its exam objectives.
Mapping certification families to job roles
Certification bodies tend to cluster around specific roles. The table below reflects the families New Horizons lists in its training catalog (Microsoft, CompTIA, Cisco, ITIL, plus professional development and project management).
| Certification family | Common focus | Roles it tends to support |
|---|---|---|
| CompTIA | Vendor-neutral fundamentals | Help desk, IT support, networking, security entry points |
| Microsoft | Microsoft cloud, productivity, and admin tools | Cloud admin, systems admin, Microsoft 365 roles |
| Cisco | Networking and infrastructure | Network engineer, network admin |
| ITIL | IT service management | Service desk, IT operations, service management |
| Project management | Project delivery methods | Project coordinator, project manager |
Vendor-neutral options like CompTIA and ITIL are designed to apply across many environments. Vendor-specific options like Microsoft and Cisco go deeper into one ecosystem. Neither is automatically better; the choice depends on what the jobs you want actually ask for.
Vendor-specific vs. vendor-neutral: how to decide
Use these conditions rather than a blanket rule:
- Choose vendor-specific when your target employers run that vendor's stack, when job postings name the credential, or when you already work in that environment and want to go deeper.
- Choose vendor-neutral when you want flexibility across employers, are early in your career and still exploring, or work in a mixed-technology environment.
- Choose both over time if your role spans layers — for example, a vendor-neutral networking or security foundation plus a vendor-specific cloud credential.
If you are unsure, look at ten job postings for your target role and note which credentials repeat. That list is your shortlist.
Check prerequisites, exam format, and renewal rules before you commit
This is where people lose time and money. Before buying training, confirm:
- Prerequisites — some certifications assume prior experience or a lower-level credential first.
- Exam format — number of questions, time limit, whether it includes hands-on labs, and where you can take it.
- Renewal or recertification — many modern certifications expire and require continuing education or a re-exam. A credential that lapses is not doing its job on your résumé.
- Cost and access — exam fees, training fees, and whether training is live instructor-led, online, or self-paced.
New Horizons describes its delivery as live instructor-led online training across Microsoft, CompTIA, Cisco, ITIL, professional development, and project management. If you learn better with a live instructor and a schedule, that format fits; if you need to study around shift work, self-paced may fit better. Match the format to how you actually study, not to what sounds most rigorous.
Building a study path
A workable path looks like this:
- Define the target role and the one or two certifications that role most often requires.
- Confirm the exam objectives from the certifying body so your study material matches the current version.
- Pick a training format — instructor-led, online, or self-paced — and block study time.
- Practice with hands-on tasks, not just reading, especially for labs-based exams.
- Schedule the exam once practice scores are consistently passing, then keep the credential current.
For teams, the same logic scales: identify the roles on your team, map each to a certification path, and align training to those paths rather than sending everyone to the same course.
Common pitfalls to avoid
- Chasing outdated certifications. Exam versions retire. Always check that the credential you are studying for is the current one.
- Using exam dumps. Brain-dump sites undermine the point of certification and can violate the certifying body's terms. Learn the material.
- Mismatched skill level. Jumping into an advanced certification without the prerequisite experience usually ends in a failed exam and wasted money.
- Treating a course as a credential. Completing training is not the same as passing the exam.
- Ignoring renewal. Budget time for continuing education so the credential stays valid.
Where to start
If you are choosing your first certification, start with a vendor-neutral foundation tied to your target role, confirm the current exam objectives, and select a training format you will actually finish. If you already work in a specific ecosystem, go vendor-specific and deepen that expertise. Either way, verify prerequisites and renewal rules before you pay for anything, and let real job postings — not marketing — tell you which credential is worth your time.
