Module Grade Data at UK Universities: What Exists, Who Holds It

Every UK university holds module-level grade data going back years. Almost none of it appears anywhere a student can find it.

Ask your module convenor for the mark distribution from last year's cohort and you'll usually get a shrug, or a vague line about "similar to previous years." That's not because the data doesn't exist — exam boards see it every summer. It's because nobody has ever built the pipeline to get it in front of the people it would actually help: you.

What module grade data actually is

When we say "module grade data," we mean the full distribution of marks a cohort received in a specific module in a specific year — not the headline degree classification, the module itself.

That includes:

• Mean and median mark for the cohort
• First-rate: the proportion of students who scored 70%+
• Fail rate: the proportion below the pass threshold
• Spread: how tightly or widely marks are distributed around the mean
• Cohort size: how many students actually sat the module

This is fundamentally different from what universities publish. Public-facing stats — Discover Uni, league tables, prospectuses — report degree-level outcomes aggregated across an entire course. They never break it down by module, because module-level data reveals something universities have historically preferred to keep opaque: which modules are easy routes to a First and which are quietly punishing.

Who holds this data, and why it stays hidden

Module grade data sits with three groups inside a university: the module convenor, the exam board, and central records (usually a "student data and analytics" team). None of them are under any obligation to publish it proactively.

That's the gap GradeHack exists to close. We hold FOI-sourced module-level grade distributions — sourced under the Freedom of Information Act, which applies to public universities in the UK regardless of whether they'd volunteer the numbers. See our FOI methodology for exactly how that process works.

Banded signal example

We never publish raw percentages on public pages (our privacy threshold excludes any cohort under 10 students, and we band everything else). Here's the shape of what a banded module signal looks like:

Signal	Band	What it tells you
First-rate	High	Well above the subject average — worth investigating further
Mean mark	High 2:1	Cohort centres just below First boundary
Cohort size	Large	Statistically stable — not a small, noisy sample
Fail rate	Low	Low downside risk if you take this module

You can read the full logic behind these bands in how does degree classification work.

Why this matters for your module choice

If module choice genuinely affects your degree classification — and it does, see does module choice affect degree class — then module grade data is the single most useful input into that decision. Everything else (interest, workload, reputation) is guesswork by comparison.

Most students choose modules with less information than they'd use to choose a phone contract. That's not a knock on students — it's a reflection of how badly this data has been locked away.

What to do with it

If you're choosing modules this year, don't rely on word of mouth alone. File your own FOI request if you have the patience (20 working days, addressed to your university's information governance team), ask your module convenor directly, or access GradeHack's FOI-sourced data to see banded signals across your subject without doing the legwork yourself.

The data exists. The only question is whether you see it before or after you've already picked your modules.
