What Is Scaled Scoring for CIMA OT Exams?

CIMA's objective tests (OTs) aren't marked as a simple percentage — they use a scaled scoring system. If you've ever wondered why your result is a number out of 150 rather than a percentage, or what counts as a pass, this guide explains how CIMA scaled scoring works, why it exists, and what it means for how you prepare. For how the OTs fit into the wider qualification, see our guide to CIMA exam dates and structure.

What is scaled scoring?

Since 2015, every CIMA objective test has used scaled scoring. The reason is that there isn't a single version of each exam — CIMA uses multiple versions of the same OT, sat by different candidates at different times. Those versions can differ very slightly in difficulty, so marking purely on the number of questions answered correctly wouldn't be fair. Scaled scoring adjusts for those minor differences so that every candidate's result is comparable, whichever version they happened to sit.

How the scaled score works

Your result is reported as a scaled score between 0 and 150, with the pass mark set at 100. To pass, you need a scaled score of 100 or more. Importantly, the passing standard is set independently for each subject — the standard for F1, say, is set separately from E1, because each exam examines different content. The 100 pass mark is the same across subjects, but the underlying standard it represents is calibrated per exam.

Why CIMA uses scaled scoring

The goal is fairness. Because candidates sit different versions of an OT on demand throughout the year, two students answering the same number of questions correctly might have faced slightly different levels of difficulty. Scaling levels that out, so no one is advantaged or disadvantaged by which version they were given or when they sat it. It's the same principle many large-scale professional and admissions exams use to keep results consistent over time.

What scaled scoring means for you

Three practical things follow from this:

• Your score isn't a raw percentage. A scaled score of 100 out of 150 does not mean you got 67% of questions right — the scale isn't a percentage, so don't try to convert it. Focus on clearing 100, not on a percentage target.
• You get a provisional result on the day. OTs are computer-marked, so you receive a provisional pass/fail result shortly after finishing, with confirmation and a topic-level feedback breakdown following from CIMA.
• Aim comfortably clear of the standard. Because the standard varies by subject and version, the safest approach is to be solidly above the pass mark across the whole syllabus rather than hoping to scrape 100.

How OT scoring differs from the Case Study

It's worth not confusing the two. The Case Study exams are also reported on a 0–150 scale, but the pass mark for a Case Study is 80, not 100, and Case Studies are human-marked rather than computer-marked. So a passing score looks different depending on whether you're sitting an objective test or a Case Study — check which exam you're preparing for so you know the standard you're aiming at.

How to make sure you pass

Because scaling rewards consistent performance, broad and even syllabus coverage matters more than going deep on a few favourite topics and weak elsewhere. Practise objective-test questions across the whole syllabus under timed conditions, and never leave questions blank — there's no negative marking, so an educated guess can only help. A structured CIMA course keeps your coverage even and your question practice high, which is exactly what the scaled system rewards.

Frequently asked questions

What is the CIMA objective test pass mark?

A scaled score of 100 out of 150. The same pass mark applies across subjects, though the underlying standard is set independently for each exam.

Is a score of 100/150 the same as 67%?

No. The scaled score isn't a percentage, so you can't convert it that way. It reflects your performance adjusted for the difficulty of the version you sat.

Why are there different versions of the same exam?

OTs are taken on demand throughout the year, so multiple versions exist. Scaled scoring keeps results comparable across those versions.

When do I get my OT result?

You receive a provisional result shortly after finishing the computer-based exam, with confirmation and feedback following from CIMA.

Does CIMA tell me which questions I got wrong?

Not question by question. You receive your scaled score plus topic-level feedback showing relative strengths and weaknesses, which is what you use to focus any resit preparation.
