CompTIA Certification Stacking
CompTIA certifications are vendor-neutral and stackable — each certification builds on the previous, creating clear career pathways in IT support, networking, security, and cloud administration.
ITF+ → A+ → Network+ → Security+
The core pathway takes you from IT fundamentals through hardware/software support, networking essentials, and security foundations. This stack is the gold standard for launching an IT career and satisfies the DoD 8570 baseline requirement.
Server+ · Linux+ · Cloud+
Infrastructure certifications validate skills in server administration, Linux systems management, and cloud deployment. These are ideal for system administrators and DevOps engineers moving beyond desktop support.
CySA+ → PenTest+ → CASP+
The cybersecurity pathway progresses from defensive analysis (CySA+) through offensive testing (PenTest+) to advanced security architecture (CASP+). CySA+ and CASP+ are approved for DoD 8570 IAT and IAM roles.
Data+ · Project+
Data+ covers data governance, analytics, and visualisation for aspiring data professionals. Project+ validates IT project management skills without requiring PMP-level experience.

CompTIA Exam Format & Question Types
CompTIA exams are known for including performance-based questions (PBQs) alongside traditional multiple-choice questions. PBQs present simulated environments where you must perform tasks like configuring a firewall, troubleshooting a network topology, or setting up a RAID array.
📊 Scoring
CompTIA uses a scaled scoring model from 100 to 900. Passing scores vary by exam — for example, A+ Core 1 requires 675, Security+ requires 750, and CySA+ requires 750. Higher-level exams typically have higher pass marks.
🔄 Renewal
CompTIA certifications are valid for three years. Renew through continuing education (CE) credits, earning a higher-level CompTIA certification, or retaking the exam. The CE programme allows you to maintain your certification through activities like training, teaching, or publishing.

Why CompTIA Certifications Matter
CompTIA certifications are globally recognised and vendor-neutral, meaning the skills you learn apply across any technology stack. They are particularly valued in government and defence sectors — CompTIA Security+, CySA+, and CASP+ meet U.S. Department of Defense Directive 8570/8140 requirements for information assurance positions.
For career starters, the A+ certification remains the most widely requested entry-level IT credential. For experienced professionals, CySA+ and PenTest+ demonstrate specialised cybersecurity skills that command premium salaries in a job market with a persistent skills shortage.
