Certified Information Systems Auditor (CISA) Practice Tests

CISA weights Information Systems Operations and Business Resilience and Protection of Information Assets tied at 26 percent each, followed by Information System Auditing Process and Governance and Management of IT tied at 18 percent each, and Information Systems Acquisition, Development and Implementation at 12 percent. This practice bank of 895 questions is built to match that split, so operations, resilience, and asset-protection scenarios get proportionally more coverage than any single domain.

On test day you face 150 questions in 4 hours, scored on a scale of 200 to 800, and you need 450 or higher to pass. Every question is multiple choice with one best answer among four options, often scenario-based rather than pure factual recall — CISA tests audit judgment, not just knowledge of controls.

As with ISACA's other certifications, passing the exam is only part of it. Full CISA certification also requires 5 or more years of IS or IT audit, control, assurance, or security work experience within CISA job practice areas, earned within the 10 years before you apply (experience waivers cover up to 3 years). If you don't yet have the experience, ISACA offers a CISA Associate designation in the meantime. The exam costs $575 for members and $760 for non-members, plus a $50 application fee once you certify. Renewal requires 120 CPE hours over a 3-year cycle, adherence to ISACA's auditing standards, and an annual maintenance fee ($45 members, $85 non-members). Start with the 30 free questions, then work through the full 895-question bank until your accuracy holds steady across all five domains.

The Certified Information Systems Auditor (CISA) is ISACA's flagship certification and the globally recognized standard for IT audit, control, assurance, and security professionals. First introduced in 1978, the credential validates a professional's ability to assess vulnerabilities, report on compliance, and institute controls within an enterprise — covering the full scope of information systems auditing, governance, acquisition, operations, and asset protection. More than 151,000 professionals worldwide currently hold the CISA designation, and it has been shortlisted for Best Professional Certification Program by SC Awards Europe and SC Awards North America in 2025.

The certification is specifically designed to demonstrate competency across five critical job practice domains: the IS auditing process, IT governance and management, IS acquisition and development, IS operations and business resilience, and protection of information assets. It has evolved to address emerging technologies including artificial intelligence, cloud computing, blockchain, and IoT security, ensuring holders remain relevant in a rapidly changing threat landscape.

CISA is designed for mid-career to senior IT and information security professionals who perform or manage audit, control, assurance, or security functions. Typical roles include IT auditors, internal auditors, IS audit managers, IT risk and compliance managers, security consultants, and IT governance officers. The certification is particularly valuable for professionals at organizations subject to regulatory oversight — such as financial services, healthcare, and government — where IT audit and compliance functions are critical.

Candidates are not required to meet experience requirements before sitting the exam, making it accessible to professionals who are transitioning into IS audit roles. However, full certification requires five or more years of professional experience in IS auditing, control, or security, making it most appropriate for those with a solid foundation in IT operations, security, or internal audit.

ISACA has no formal educational prerequisites for sitting the CISA exam itself — any candidate may register and attempt the exam regardless of background. However, to achieve full CISA certification after passing, candidates must demonstrate a minimum of five years of professional work experience in information systems auditing, control, assurance, or security. This experience must be verified and submitted within five years of passing the exam.

ISACA offers experience waivers of up to three years for candidates who hold a relevant university degree (two-year or four-year), a graduate degree in IS or IT, or other recognized certifications such as CISM, CISSP, or CRISC. Recommended knowledge before attempting the exam includes a solid understanding of IT infrastructure, information security fundamentals, risk management frameworks (such as COBIT or NIST), and basic business auditing principles. Most successful candidates have at least two to three years of hands-on IT or audit experience prior to sitting the exam.

The CISA exam consists of 150 multiple-choice questions, all with four answer options (A, B, C, D), to be completed in 240 minutes (4 hours). Questions are a mix of knowledge-based items testing recall of frameworks and standards, and scenario-based questions — which typically comprise 60–70% of the exam — requiring candidates to apply audit principles to realistic workplace situations. A small number of questions are unscored research items used for future exam development and do not affect a candidate's score.

The exam is delivered via computer-based testing (CBT) at authorized PSI testing centers worldwide, or as a remotely proctored online exam. Scores are reported on a scale of 200 to 800, with a passing score of 450. The scaled scoring model accounts for question difficulty, so harder questions carry more weight. There is no penalty for incorrect answers. Preliminary pass/fail results are available immediately upon exam completion, with official scores typically posted to a candidate's ISACA account within 5–7 business days. Candidates who do not pass must wait 30 days before retaking and may sit the exam up to four times within a rolling 12-month period.

CISA consistently ranks among the highest-paying IT certifications globally. ISACA reports that CISA holders earn an average annual salary of US$149,000, and 22% of certified professionals report receiving a pay increase following certification. The credential opens doors to senior roles including IT Audit Manager, IS Audit Director, Chief Information Security Officer (CISO), IT Risk Manager, and Compliance Officer across industries with heavy regulatory requirements such as financial services, healthcare, government, and critical infrastructure.

The CISA's international recognition — backed by ISACA's global presence and more than four decades of credentialing history — makes it particularly valuable for professionals working in multinational organizations or seeking roles across different regulatory jurisdictions. Compared to alternatives such as the Certified Internal Auditor (CIA) or CRISC, CISA's specific focus on IS audit and control gives it a distinct advantage in technology-forward audit functions. Seventy percent of CISA holders report measurable on-the-job improvement after certification, reflecting the credential's direct applicability to daily audit and governance responsibilities.
