University Grade Distribution – The Data UK Universities Hide

Every UK university has it: raw data on how students performed in each module, how many got a First, a 2:1, a 2:2. The distribution of grades, semester by semester, module by module, cohort by cohort.

But you've never seen it, and there's a reason.

Grade distribution data is public under the Freedom of Information Act, but universities rarely volunteer it. Yet FOI requests reveal patterns that institutions would rather keep hidden — and that information could fundamentally change how you approach module selection.

What is grade distribution data?

Grade distribution data is the raw counts and percentages of students who achieved each classification or mark range in a module, across a cohort.

For example:

Module	First	2:1	2:2	3rd	Pass	Fail	Mean Mark	Cohort Size
CS101 - Algorithms (Y1)	12%	38%	35%	12%	3%	0%	63%	125 students
CS102 - Databases (Y1)	2%	28%	52%	15%	3%	0%	58%	125 students
CS201 - Systems (Y2)	20%	45%	28%	5%	2%	0%	66%	110 students

This tells you which modules are "easier" (higher First rates), which are notoriously hard, how difficult Y2 is versus Y1, and how your cohort compares to historical baselines.

Why universities don't publish it

Universities don't voluntarily publish grade distribution data for several reasons:

Reputational concern: If one university publishes that only 5% of students in Engineering get a First, while another publishes 22%, the comparison is damaging. The optics suggest one institution is "harder" or has "worse" standards — even if both reflect different quality profiles.

Recruitment risk: Transparent grade distribution would reveal "which degrees are easier to get a First in." Universities want to attract students based on prestige, not on grade difficulty.

Regulatory invisibility: By not publishing data, universities maintain that a 2:1 "means the same thing" everywhere. Publishing distributions would expose that a 2:1 is 60% at one university and 70% at another.

League table gaming: UK league tables include the proportion of graduates achieving First or 2:1. Rising First rates look like "improved student quality" — publishing would expose whether standards actually dropped.

How FOI requests work

Despite the lack of voluntary transparency, grade distribution data is legally public under the Freedom of Information Act 2000. Any UK resident can request it.

A typical FOI request asks:

"For the past three academic years, please provide the number and percentage of students achieving First-class, upper second-class, lower second-class, third-class, and fail classifications in [degree name] by module. Include mean marks and cohort sizes."

The university has 20 working days to respond (extendable to 60 days for complex cases).

Response patterns:

• Most universities comply, but often suppress data for cohorts under 10 students (anonymity protection) or aggregate by year rather than module.
• Some push back, claiming module-level data is "too sensitive" or would breach anonymity — often overstated.
• A few refuse outright. You can appeal to the Information Commissioner's Office (ICO) if denied.

What the data actually reveals

FOI requests to UK universities show patterns universities would rather hide:

Pattern 1: Huge variance between modules

At a given university in a given degree, some modules have 40% achieving 2:1 or higher; others have only 10%. Module A (Y2 elective) might have 28% First and 48% 2:1 (76% total at 2:1+), while Module B (Y2 core) has 5% First and 32% 2:1 (37% total). Choosing A over B materially affects your degree outcome.

Pattern 2: Grade inflation year-on-year

Most universities show rising First rates over time. In 2010–11, ~8% of undergrads nationally got a First. By 2024, it was ~20%. This could reflect rising quality or dropping standards — the data alone doesn't distinguish.

Pattern 3: Subject-level divergence

STEM subjects have lower First rates than humanities in the same university. Economics has lower First rates than History. These reflect disciplinary differences in assessment and marking, not student quality.

Pattern 4: Suppression of small cohorts

Universities suppress module-level data for cohorts under 10 students, protecting anonymity. This means small Year 1 modules are often hidden.

Why this matters for students

If you know a module's grade distribution before choosing it, you have actionable information:

• Choose modules where you're more likely to achieve your target mark.
• Calibrate risk — take a harder module in Y2 (counts less) and an easier module in Y3 (counts more).
• See which modules align with your capabilities.

Without this data, you're choosing blind.

GradeHack's approach

We're building a database of module-level grade distributions from FOI requests to UK universities:

• Public, banded data: Show distributions as bands (low / mid / high First rate) rather than raw percentages, protecting anonymity while providing transparency.
• Searchable by university, degree, and module: Find relevant data.
• Historical trends: See how module difficulty shifted over three years.
• Authenticated access: Logged-in users see more detail.

This lets you make informed module choices — the data universities have been hiding.

The legal path

FOI requests for grade distribution are legally sound. If your university refuses:

1. Request a refusal review (within 40 days of refusal).
2. If refused again, escalate to the Information Commissioner's Office (ICO).
3. The ICO investigates; if the university is wrong, they compel disclosure.

This process takes 6–12 months. Having an aggregated source (like GradeHack) is valuable — you don't have to fight university by university.

Bottom line

Grade distribution data exists at every UK university. It's legally public. But universities avoid publishing it because it reveals uncomfortable truths: module difficulty varies wildly, standards diverge by institution, and some "prestigious" universities award higher First rates than more rigorous ones.

By making this data transparent, GradeHack aims to flip the power dynamic. You shouldn't have to FOI your own university to understand which modules are achievable and which are notoriously hard. That data should be available when you're planning your degree.
