Grade Boundaries GCSE Edexcel 2025: Everything you need to know

Grade boundaries are the raw mark thresholds students need to reach for each grade in an exam series. They are not set in advance. Edexcel (Pearson), like every regulated exam board in England, finalises them after marking is complete, based on how that year's cohort actually performed against the difficulty of the papers.

For reformed 9-1 GCSEs, the boundaries are published in raw marks, not percentages. The total raw mark differs between subjects: Maths uses a 240 scale, English Language and Literature use 160, History uses 168 and Religious Studies B uses 204. That means a mark of 100 means very different things in different subjects.

This guide pulls together the published June 2025 Edexcel GCSE boundaries for the twelve most-entered subjects, explains how the boundaries are set, and looks at what the numbers suggest for students sitting their exams in summer 2026.

A grade boundary is the minimum raw mark needed to achieve a particular grade. For linear GCSEs, the boundaries apply to the total mark across every paper in the subject, not to any single paper on its own. If you scored brilliantly on Paper 1 and badly on Paper 2, what counts is the combined total against the qualification boundary.

Edexcel publishes the boundaries on results day in raw marks out of the qualification's maximum. There is no UMS conversion under the reformed 9-1 system: The number you see is the actual mark on the paper. For tiered subjects such as Maths and the separate sciences, Foundation tier covers grades 1 to 5 and Higher tier covers grades 4 to 9.

Boundaries shift every year. A harder paper produces lower boundaries and an easier paper produces higher ones. The aim is that a grade 5 in 2025 represents the same standard as a grade 5 in 2024, even when the raw marks needed are different.

Edexcel does not set its boundaries in isolation. The exams regulator Ofqual oversees the process and applies a principle called comparable outcomes. The idea is that the proportion of students achieving each grade should stay broadly in line with previous years, unless there is strong evidence the cohort is genuinely stronger or weaker.

Senior examiners review scripts at key grade thresholds and use statistical predictions, anchored to the cohort's prior attainment at primary school, to set the boundaries. Where examiner judgement and statistics disagree, the awarding committee weighs both. Small shifts in boundaries can move thousands of students between grades, so the process is taken seriously.

This is why boundaries differ between exam boards. An Edexcel grade 7 in History and an AQA grade 7 in History represent the same standard of achievement, but the raw marks needed will not be identical because the papers themselves are different in length, content and style.

The table below shows the published June 2025 boundaries for the twelve most-entered Edexcel GCSE subjects. Marks are out of the qualification's total maximum. Grades 7 and 9 are not available on Foundation tier papers, so those cells are marked N/A. Grade 1 is not awarded on Higher tier in tiered subjects: The lowest reported Higher grade is 3, with anything below that recorded as ungraded.

Maths Higher in 2025 needed 217 out of 240 for a grade 9, which is just over 90 per cent of the raw marks across the three papers. A grade 7 came in at 156, around 65 per cent. The grade 4 standard pass on Higher tier needed only 53 marks, around 22 per cent. That huge gap between the bottom and top of the Higher paper is the design point: Examiners want clear differentiation at the top end, so almost every mark in the second half of a Higher paper is fighting for a top grade.

On the Foundation tier, a grade 5 strong pass required 175 marks and a grade 4 standard pass required 144. Those are high in percentage terms, around 73 per cent and 60 per cent respectively. Foundation tier students aiming for a grade 5 cannot afford to leave easy marks on the table.

English Language asked for 131 out of 160 for a grade 9 and 95 for a grade 5. English Literature was harder at the top: A grade 9 needed 135 of 160, which is about 84 per cent of raw marks. The grade 4 standard pass in English Literature sat at 73, around 46 per cent.

Combined Science is the big paper of the GCSE suite, with six papers totalling 360 marks. A grade 9-9 needed 284 of 360, a grade 5-5 needed 227 and a grade 4-4 standard pass needed 207. Because the qualification reports double grades (such as 7-6 or 5-5), the boundary table looks busier than a single-grade subject, but the per-grade thresholds for the Higher tier follow the same shape as the separate sciences.

For the separate sciences on Higher tier, all three out of 200 marks: Biology needed 167 for a grade 9 (around 84 per cent), Chemistry needed 161 and Physics needed 161. The grade 4 standard pass was lowest in Chemistry at 62 marks, around 31 per cent. That gap between a grade 9 and a grade 4 again reflects how Higher tier papers are designed to discriminate.

History and the geographies sit on different scales. History uses a 168 mark total: A grade 9 cost 146 marks on the option used in our table, around 87 per cent. Geography A and Geography B both use 256 marks, but Geography B was harder at the top in 2025, with a grade 9 boundary at 217 versus Geography A at 206.

A key takeaway is that you should not rely heavily on the boundaries from the COVID-era series. The 2020, 2021 and 2022 boundaries were lower because of disrupted teaching and the move to teacher-assessed grades. The 2024 and 2025 series mark a return to something close to the pre-pandemic baseline, and in some subjects boundaries are now sitting at or above where they were in 2019.

If you are sitting Edexcel GCSE Maths Higher in 2026, working back from the 2025 grade 9 threshold of 217 out of 240 is more realistic than averaging across the past five years. Build your past paper practice around that target. Aim to consistently score above the recent grade 9 threshold on past papers under timed conditions, not just to scrape it once on a good day.

For the sciences, the gap between grade 4 and grade 9 is wide. That means small gains in the hardest content can move you up an entire grade. Focus your last few weeks on the topics that tend to appear on the back end of the paper: Required practicals, longer six-mark questions and the maths skills carried across from KS3.

For History and Religious Studies B, watch the option-specific boundaries. A few marks across a 168 mark paper can move you between grade 7 and grade 8, so essay structure and command word accuracy on the longer extracts matter more than rushing to cover every topic. Rehearsing PEEL paragraphs against the mark scheme tends to beat another sweep through your knowledge organisers in the final fortnight.

For English Language and English Literature, the gap between grade 5 and grade 9 is roughly 35 to 40 marks out of 160. That sounds tight, but each mark is genuinely fightable. Practising the higher assessment objectives, particularly methods analysis on Language Paper 1 and contextual links on Literature, is where most students gain real ground in the final few weeks before the exam.
