Open Book vs Closed Book IT Certification Exams: What’s Changing in 2026 and How to Prepare?
The world of IT certification exams is evolving rapidly in 2026. One of the biggest changes candidates are noticing is the shift in exam formats — particularly the rise of open book exams alongside traditional closed book formats. This shift has created confusion among candidates about how to prepare effectively and what strategies actually work.
For years, most IT certification exams were strictly closed book, requiring candidates to memorize concepts, commands, and configurations. However, modern certification bodies are now focusing more on real-world skills, problem-solving ability, and practical application of knowledge. This is where open book exams are gaining attention.
But here's the reality:
Whether it's open book or closed book, passing the exam still requires smart preparation — not just access to information.
In this article, we will break down the differences between open book and closed book certification exams, explain what's changing in 2026, and show you exactly how to prepare for both formats effectively.
What Are Closed Book IT Certification Exams?
Closed book exams are the traditional format where candidates are not allowed to refer to any external materials during the exam. Everything must be recalled from memory.
✔ Key Characteristics:
- No access to notes or documentation
- Focus on memorization and recall
- Time pressure is high
- Questions test both theory and application
✔ Examples of Skills Tested:
- Commands and syntax
- Definitions and concepts
- Configuration steps
- Best practices
✔ Challenges:
Many candidates fail closed book exams because:
- They rely too much on passive learning
- They don't practice enough questions
- They struggle with time management
Closed book exams demand strong conceptual clarity + fast recall ability.
What Are Open Book IT Certification Exams?
Open book exams allow candidates to access certain materials during the exam. This could include documentation, reference guides, or official resources.
✔ Key Characteristics:
- Access to limited or controlled resources
- Focus on problem-solving

"If it's open book, I don't need to study much."
👉 This is the biggest mistake.
✔ Reality:
- Time is still limited
- Searching for answers wastes time
- Questions are designed to test understanding, not lookup skills
