UK Grading System Explained

GCSEs (General Certificate of Secondary Education) are the qualifications English students take at age 16, typically across 8–10 subjects. Since 2017, England has used a 9–1 numeric grading scale, with 9 the highest and 1 the lowest. A U (ungraded) indicates the result was below the minimum standard. This replaced the old A*–G letter scale that had been in place for decades.

The new scale was designed so that the top grades differentiate more finely among the highest-performing students. The official comparison points are approximate equivalences at grade boundaries, not a direct one-to-one mapping: the bottom of grade 7 is comparable to the bottom of the old grade A; the bottom of grade 4 is comparable to the bottom of the old grade C; and the bottom of grade 1 is comparable to the bottom of the old grade G.

Grade 4 is generally treated as the minimum acceptable pass — equivalent to the old grade C requirement that many employers and colleges used. Grade 5 is sometimes referred to as a “strong pass” and is used as a higher benchmark by some schools and employers.

A-Levels (Advanced Level) are the subject-based qualifications that English students take at age 18, typically in three or four subjects. They are the standard pathway to university. A-Levels are graded from A* (the highest) down to E (the lowest passing grade), with U for unclassified results (a fail).

Each grade also converts to UCAS Tariff points, which universities use for admissions — see our full UCAS Tariff Points Table for every grade and qualification type.

UK undergraduate degrees are classified into bands based on overall mark percentages. The system applies to bachelor's degrees (BA, BSc, BEng, etc.) across England, Wales, and Northern Ireland. Scotland uses a similar but not identical classification system.

There is no single official conversion between UK degree classifications and US GPA. The UK uses class-based bands (First, 2:1, 2:2, Third) rather than a continuous grade-point average, and the underlying percentage scales are not directly comparable — a 70% in the UK is a First (the highest class), while a 70% in the US is typically a C-minus.

US institutions and employers that need a formal equivalency typically use a recognised credential evaluation service, such as a member of NACES (the National Association of Credential Evaluation Services), rather than relying on a fixed public table. The evaluation accounts for the institution attended, the degree classification, and the specific context of the programme.

Qualitatively, a First is generally regarded as a strong, top-tier result, broadly comparable to the upper end of the US GPA scale. A 2:1 is typically seen as a solid, above-average result. But these are rough impressions, not precise equivalents — we are deliberately not providing a fabricated conversion table, because no official one exists.
