CISA Exam Difficulty: What to Expect and How to Pass
Understand the format, passing score, and difficulty of the ISACA CISA exam. Expert tips to pass on your first attempt.
The Certified Information Systems Auditor (CISA) by ISACA is the undisputed heavyweight certification for IT auditors. But it has a reputation: it's notoriously difficult.
How Difficult is the CISA?
The CISA is challenging because it requires a hybrid mindset. You cannot just be a technical expert, and you cannot just be an auditor. You must be both.
The exam consists of 150 multiple-choice questions over 4 hours.
The "ISACA Mindset"
The primary reason candidates fail is not a lack of technical knowledge, but failing to apply the "ISACA mindset." When answering questions: 1. Safety First: Human life always takes precedence over data or systems. 2. Business Alignment: IT exists to support the business. The best technical solution is wrong if it doesn't align with business goals. 3. Understand Your Role: You are an auditor, not an engineer. Your job is to recommend and assess, not to fix the router.
The Grading Scale
ISACA uses a scaled scoring system from 200 to 800. A passing score is 450. This does not mean you need 45% or 56%. The scale is weighted based on the difficulty of the questions.
The 5 Domains
- Domain 5 (Protection of Information Assets): Heavily weighted and technically dense.
- Domain 1 (Process of Auditing Information Systems): The foundation of the ISACA mindset.
