Are ACCA Exams Marked on a Curve?

No. ACCA exams are not marked on a curve. There is no quota of passes, no scaling to a target pass rate, and no adjustment based on how everyone else performed. The pass mark is a fixed 50%, and your script is judged against a set marking standard — not against the other candidates in the room.

What is the difference between a curve and ACCA's approach?

Curved, or norm-referenced, marking passes a set proportion of candidates — the top group passes regardless of their absolute score. ACCA uses criterion-referenced marking instead: there is a defined standard of competence, and everyone who meets it passes. In theory, everyone sitting a paper could pass, or everyone could fail — the outcome depends only on whether each script reaches the standard.

Then why do pass rates vary so much?

• Different papers are genuinely different in difficulty, so more candidates reach the standard on some than others.
• The mix of well-prepared and under-prepared candidates changes from sitting to sitting.
• Exam technique varies — the standard rewards applied, structured answers, which many candidates never practise.

The reassuring part is that your pass depends entirely on you, not on beating anyone else. If your answers hit the standard, you pass. The practical way to check whether they do is to mark your work against the official scheme — which is exactly what The 50% Club lets you do, so you know you have cleared the bar before you sit.
