How to Get IT Certifications: A Practical Guide to Starting and Advancing
IT certifications are among the most direct ways to demonstrate technical competence — whether you're breaking into the industry, pivoting to a new specialty, or validating skills you've been using on the job for years. But the path from "I want a certification" to actually holding one involves more decisions than most people expect.
What IT Certifications Actually Are
An IT certification is a credential issued by a vendor, industry organization, or standards body that confirms you've passed an exam (and sometimes met other requirements) in a specific technical area. They're not degrees — they don't require years of coursework — but serious certifications do require meaningful preparation.
Certifications fall into two broad camps:
- Vendor-neutral certifications — issued by organizations like CompTIA, (ISC)², or ISACA. These focus on concepts, principles, and practices that apply across tools and platforms.
- Vendor-specific certifications — issued by companies like Microsoft, AWS, Google, Cisco, or Salesforce. These validate skills in that vendor's specific ecosystem.
Both types carry real weight, but in different contexts. A vendor-neutral cert like CompTIA Security+ signals broad foundational knowledge. A vendor-specific cert like AWS Certified Solutions Architect signals deep, practical fluency in a specific environment.
The General Process for Getting Certified 🎯
While every certification has its own requirements, the process follows a recognizable pattern:
1. Choose a Certification Track
Start by identifying which domain interests you — networking, cybersecurity, cloud, development, data, IT support — and which certifications are recognized in that space. Research job postings in your target role and note which credentials employers actually list.
2. Check Prerequisites
Some certifications have formal prerequisites (you must hold another cert or prove years of experience before sitting the exam). Others are open to anyone. Skipping this step can mean failing an exam you weren't ready for, or paying for a cert that doesn't qualify you for the next level.
3. Register Through the Issuing Body
Most certifications are administered through third-party testing platforms — Pearson VUE and Prometric handle the majority of major IT exams. You register, pay the exam fee, and schedule a time at a test center or, increasingly, through an online proctored session from home.
4. Study and Prepare
This is where time investment varies dramatically. Entry-level exams might require 4–8 weeks of focused study. Expert-level certifications from Cisco (like the CCIE) or (ISC)² (like the CISSP) can require months of preparation and hands-on lab work.
Common study resources include:
- Official exam guides published by the certification body
- Video courses on platforms like Pluralsight, LinkedIn Learning, or Udemy
- Practice exams (these are especially valuable for understanding question format)
- Hands-on labs and sandboxes for technical domains
5. Take the Exam
Exams are typically multiple choice, though higher-level certifications often include performance-based questions — simulations where you configure actual systems rather than just select answers.
6. Maintain the Certification
Most certifications expire. CompTIA certs renew every three years. Cisco certs have renewal cycles tied to their tier. AWS certifications expire after three years. Renewal usually means either retaking the exam or earning Continuing Education (CE) credits through ongoing learning activities.
Factors That Shape Your Path
No two people follow exactly the same route, because several variables affect which certifications make sense and how hard they are to get:
| Variable | Why It Matters |
|---|---|
| Current experience level | Beginners often need foundational certs before advanced ones are realistic |
| Existing job role | Some certifications align directly with your current work and study faster |
| Target job market | Government and defense roles often prioritize specific certs (e.g., DoD 8570 compliance) |
| Budget | Exam fees range from under $100 to over $700; training materials add more |
| Vendor environment | If your workplace runs Azure, an Azure cert is more immediately applicable than AWS |
| Learning style | Self-paced study, bootcamps, and employer-sponsored training all lead to the same exam |
Entry Points Vary Widely
Someone with no IT background will likely start with something like CompTIA A+ (hardware/software fundamentals) or Google IT Support Professional Certificate — accessible credentials that establish baseline competency.
A developer moving into cloud infrastructure might go straight to an associate-level cloud cert without touching entry-level IT support credentials at all.
A security professional with years of experience might pursue CISSP — which requires five years of verified work experience in addition to passing the exam.
The same destination (a high-level certification) can have dramatically different starting points, timelines, and costs depending on where someone begins.
What the Credential Ladder Looks Like 📋
Most major certification programs are tiered:
- Foundational/Entry — concepts, terminology, basic troubleshooting
- Associate — practical skills, role-specific knowledge
- Professional/Expert — deep technical competency, often scenario-based
- Specialty — narrow focus within a broader domain (e.g., cloud security vs. general cloud)
Trying to skip levels without the underlying knowledge usually shows up on exam day.
The Missing Piece Is Always Your Situation
Understanding how certifications work — the registration process, study requirements, renewal cycles, and how vendor-specific and vendor-neutral credentials differ — gives you a real foundation for planning. But which certification to pursue first, how long it will realistically take, and whether the cost-to-benefit ratio makes sense right now all depend on where you are in your career, what tools you're already working with, and what roles you're actually targeting.
