ExploreAbout this exam
The IAB Professional Practice exam is a four-domain assessment for bookkeepers, payroll specialists and accountants working in or toward UK practice. The four domains are weighted equally at 25% each: Anti-Money Laundering Supervision, Bookkeeping, Payroll, and Accounting. The credential sits within a body that describes itself as an Ofqual regulated awarding organisation, an HM Treasury appointed AML supervisor overseen by OPBAS, and a professional membership organisation founded in 1973 with three professional grades (AIAB, MIAB and FIAB). Candidates should note that the published source does not state the number of questions, the exam duration, the passing score, the fee, the retake policy or the validity period, so those details must be confirmed directly with the awarding organisation before booking. Preparation should follow the domain weights rather than personal comfort: AML Supervision carries the same weight as each technical area, so candidates who focus only on double entry and payroll calculations leave a quarter of the paper under-prepared. Build a study plan that covers the Money Laundering Regulations 2017 supervisory framework, including who must be supervised and the choice between HMRC and a professional body supervisor such as the IAB; core bookkeeping and accounting principles through to final accounts; and payroll processing including statutory deductions and employer obligations. Work through practice calculations under timed conditions, because the technical domains reward accuracy and speed rather than recall alone. Confirm current syllabus and assessment details with the IAB before finalising your revision timetable.
What you'll study
About IAB Professional Practice preparation
What does the exam cover?
Four equally weighted domains at 25% each: Anti-Money Laundering Supervision, Bookkeeping, Payroll, and Accounting. AML is not a minor add-on, so treat supervisory obligations, risk assessment and client due diligence as a full quarter of your revision rather than background reading.
How many questions are there and how long do I get?
The published source does not state the question count or the duration. Confirm both with the awarding organisation before you book, then practise full-length papers under the stated time so your pacing is realistic rather than assumed.
What is the pass mark?
The source does not publish a passing score, so no figure is given here. Ask the awarding organisation directly for the current pass standard and whether it is a fixed mark or scaled. Do not rely on figures quoted in forums, which often refer to older syllabus versions.
Which domain should I study first?
Start with AML Supervision, because it is the area most candidates underestimate and it carries the same 25% weight as the technical domains. Then alternate bookkeeping and accounting, which share underlying principles, and finish with payroll, which has the most distinct procedural detail.
How difficult is the exam?
Difficulty is not published, but the equal weighting means a candidate who is strong in bookkeeping alone cannot pass comfortably. The main risk is uneven preparation. Aim for competence across all four domains rather than excellence in two, and test yourself on the weakest domain weekly.
Can I retake it, and how long does the result last?
The source does not state a retake policy or a validity period, so neither is asserted here. Confirm both with the awarding organisation before booking, particularly if your employer or an AML supervisor will rely on the result for a defined period.
Do I need an IAB qualification or membership to sit it?
The source states you do not need an IAB qualification to join the body, and experienced practitioners can join through the experience route. Whether membership is required for the exam itself is not stated, so check eligibility with the awarding organisation first.
What are the most common failure modes?
Under-preparing AML Supervision, rushing payroll calculations, and misreading dates or deadlines in procedural questions. Another frequent problem is memorising rules without practising application. Work through scenario questions and check every figure twice before moving on.
How should I structure the final weeks of revision?
Use timed mixed-domain papers rather than single-topic blocks, because the real paper switches subject without warning. Review every wrong answer to its underlying rule, keep a one-page error log per domain, and spend the last week on your two weakest domains rather than re-reading familiar material.
