About this exam

The Certified Information Systems Auditor (CISA) credential, awarded by ISACA, is described by ISACA as the standard of achievement for auditing, monitoring and assessing IT and business systems. It is aimed at IT audit, assurance, control and security professionals who assess technology risk, and holders agree to ISACA's Code of Professional Ethics and to the Information Systems Auditing Standards. The exam covers five domains: the information systems auditing process; governance and management of IT; information systems acquisition, development and implementation; information systems operations and business resilience; and protection of information assets. ISACA states the certification also addresses emerging technologies such as AI and blockchain. Exams are computer-based and delivered at authorized PSI testing centers globally or by remote proctoring, and registration is continuous. Passing the exam is only the first step: certification also requires five years of relevant professional experience gained within the preceding ten years, a one-time US$50 application processing fee, and an application submitted within five years of passing. To prepare, ISACA offers a review manual, an online review course, a questions/answers/explanations database, a free ten-question practice quiz and member study groups. The practice questions on this page are original, independently written material and are not affiliated with, endorsed by, or drawn from ISACA.

What you'll study

Common questions

About CISA preparation

What does the CISA exam cover?

ISACA lists five domains: Information Systems Auditing Process; Governance and Management of Information Technology; Information Systems Acquisition, Development & Implementation; Information Systems Operations and Business Resilience; and Protection of Information Assets. ISACA also states that CISA addresses innovations such as AI and blockchain, so expect emerging-technology context within those domains rather than as a separate area.

How much does it cost to take the exam?

ISACA lists the exam cost as US$575.00 for members and US$760.00 for non-members. Certification also involves a one-time US$50 application processing fee, payable after your official exam scores are released, before you submit the certification application. Membership pricing is worth comparing against the non-member rate if you are registering soon.

What is the exam format and where can I sit it?

ISACA states its CISA exams are computer-based and administered at authorized PSI testing centers globally, or as remotely proctored exams. You schedule through the PSI dashboard, reached from your ISACA account under Certification & CPE Management. Verify test site availability and check system compatibility before registering, particularly if you intend to test remotely.

How long do I have to sit the exam after registering?

Registration opens a six-month eligibility period: from the date you register, you have six months to take the exam. Eligibility is established at registration and is required to schedule. Exam registration is continuous, and you can schedule as early as 48 hours after paying the registration fee, subject to appointment availability.

How far ahead can I book an appointment, and can I reschedule?

Appointments are only available 90 days in advance, so if your preferred site or date is not showing, check back closer to the date. You can reschedule without penalty during your eligibility period if you do so at least 48 hours before your scheduled appointment, following the steps in ISACA's Scheduling Guide.

Do I need the work experience before I take the exam?

No. ISACA states the exam is open to anyone interested in information security, and you may sit it before meeting the experience requirement. Certification requires at least five years of professional information systems auditing, control or security work experience, gained within the 10-year period preceding your application, and you must apply within five years of passing.

How many questions are on the exam and what is the passing score?

We could not confirm this from ISACA's published pages: the exam content page returned an error when retrieved, so question count, seat time, item formats and the passing score are not stated here. Treat any figure you see elsewhere as unverified and confirm current details in ISACA's official exam candidate guide before booking.

What happens if I do not pass - can I retake it?

The ISACA pages reviewed do not publish retake terms such as waiting periods or fees, so we cannot state them here. What is confirmed: registration is continuous with no restrictions, and each registration carries a six-month eligibility period. Check ISACA's exam candidate guide and terms of use for current retake rules before you plan a second attempt.

How is the certification maintained once I am certified?

ISACA requires at least 120 Continuing Professional Development (CPE) hours over a three-year reporting period, with a minimum of 20 CPE hours each year. CPEs that satisfy requirements for other ISACA certifications may also count toward those designations. You also continue to adhere to the Code of Professional Ethics and the Information Systems Auditing Standards.

How should I structure my study and what are common pitfalls?

Work domain by domain against the five areas, and weight time toward the ones where practice scores are weakest rather than rereading familiar material. Use ISACA's review manual, online review course, questions/answers/explanations database, free ten-question quiz and member study groups. Common failure modes are memorizing definitions instead of practising scenario judgement, and delaying booking until the six-month eligibility window is nearly gone.
