The GCSE Grading System: A Comprehensive Guide for Parents

Since the introduction of the new 9-1 numerical grading system back in 2017, parents may find themselves asking, "What do these numbers actually mean?" In this guide, we’ll break down the GCSE grade boundaries and explain how they work.

What are the 9-1 GCSE grades?

If you're a parent trying to make sense of your child's GCSE results, you might have noticed that traditional A*–G grades have been replaced with a new number-based system. This change began back in 2017, starting with English and maths, and by 2020 it applied to all GCSE subjects. Grades now range from 9, the highest, to 1, the lowest, with a 'U' meaning the student didn’t achieve a grade. These changes were introduced as part of a wider update to the school curriculum in England, aiming to raise standards and make the qualifications more rigorous.

The Shift from Letters to Numbers: Why the Change?

The goal of this change was to provide more differentiation between students, especially at the top end of the scale, making it clearer who had achieved higher levels of mastery in their subjects.

According to Ofqual, the government body responsible for regulating exams, the new grading system aims to better reflect the abilities of students. The content of GCSEs has also become more challenging, which means fewer students will achieve the top grades compared to the previous A* grade under the old system.

2.1

Contextualising the Change

The reforms to GCSE grading were part of a broader overhaul of the education system, initiated by the then-Education Secretary, Michael Gove, in 2014. The main aim was to increase the rigour of GCSE qualifications, ensuring that they better prepare students for further education and employment. By shifting the emphasis away from coursework and towards final exams, the changes sought to create a more challenging curriculum and provide a more accurate reflection of student achievement.

The new 9-1 system also helps employers and universities easily identify whether students have taken the more demanding reformed GCSEs as opposed to the older versions.

GCSE Grades Equivalent: Old vs. New

To put the new numerical grades into context...


Grade Description
Grade 9 Higher than an A* under the old system, awarded to the very highest performers.
Grade 8 Equivalent to the middle of the old A* and A grades.
Grade 7 Comparable to a solid A.
Grade 6 Slightly above a B.
Grade 5 Between a B and C—this is considered a "strong pass."
Grade 4 Equivalent to a C, often referred to as a "standard pass."
Grade 3 Between a D and E, indicating performance below a standard pass.
Grade 2 Between an E and F.
Grade 1 Between an F and G.


One of the most notable aspects of the new system is that a Grade 9 is specifically designed to differentiate the very top achievers, making it tougher to earn than the old A*. This shift aligns with a wider effort to make GCSEs more challenging and better suited to assess high-achieving students.

How are Grade Boundaries Decided?

GCSE grade boundaries are not fixed and can change year by year. Each exam board (such as Pearson Edexcel, AQA, and OCR) determines the specific marks required for each grade after the exams are completed. The boundaries are set based on the difficulty of the exam and how students performed overall, ensuring fairness in marking.

On results day, the grade boundaries are published by the exam boards, allowing students and parents to see how many marks were needed to achieve a specific grade. It’s important to note that these boundaries can vary between subjects and exam boards. For example, you can view the Pearson/Edexcel grade boundaries here, and the AQA boundaries here.

What grade do pupils need to pass their GCSEs?

A common question among parents is, "What grade is considered a pass?" Under the new system:

Grade 4 is seen as a "standard pass." This is roughly equivalent to a C in the old system, and students who achieve a Grade 4 or above have technically passed.

Grade 5, on the other hand, is regarded as a "strong pass." Many sixth forms and colleges require students to have at least a Grade 5 in core subjects like English and Maths to continue with A-Levels or other qualifications.

While Grades 1-3 count as passes on a technical level, they often don't meet the entry requirements for further education. Students who score below a 4 in English and Maths are usually required to resit these subjects the following year.

GCSE Grading System in England

The shift to numerical GCSE grades was introduced as part of a major curriculum reform in 2014, led by then-Education Secretary Michael Gove. One of the key changes was a move away from coursework-heavy assessment, placing a stronger focus on final exams to determine students' results.

These revamped qualifications were intentionally designed to be more rigorous. Instead of being assessed in stages through modules, students now study over two full years before sitting their exams. This was meant to encourage deeper learning and better long-term understanding.

According to the government at the time, the new 9–1 grading scale was introduced to better reflect the performance of top students, with more levels of distinction at the higher end. It was also intended to help employers and others clearly identify whether a student had taken the newer, tougher GCSEs or an older version of the qualification.

GCSE Grading System in Wales

In Wales, updated GCSE courses were launched in September 2015, bringing changes to both content and assessment methods. The most significant updates were made to English language, Welsh language, and mathematics, with an emphasis on improving literacy and numeracy skills.

Unlike England, however, Wales chose to keep the traditional A–G grading system*. This means that while the curriculum has evolved, the way students' performance is reported has remained familiar to both parents and employers.

GCSE Grading System in Northern Ireland

GCSE grading in Northern Ireland has also evolved in recent years. In summer 2019, the Council for the Curriculum, Examinations and Assessment (CCEA) introduced a revised system using a nine-grade scale from A to G*, with a new grade C* added to provide more clarity around pass levels.

However, not all students in Northern Ireland will receive grades on this A* to G scale. Those who take GCSEs through English exam boards may still receive numerical grades from 9 to 1, depending on the awarding body.

The CCEA has published guidance to help explain how these changes work and what the different grading systems mean for students and parents.

How the Pandemic Impacted GCSE Grades

The effects of the pandemic have significantly shaped recent GCSE results. In 2020 and 2021, traditional exams were cancelled, and grades were awarded based on teacher assessments. This led to an unprecedented spike in the number of higher grades being awarded. For instance, the proportion of students achieving grades 7 and above increased noticeably during this period. However, as exams resumed in 2022, the exam boards began recalibrating results, aiming to gradually return to pre-pandemic levels. This trend has continued into 2023 and 2024, with fewer top grades (9-5) being awarded and a rise in the proportion of lower grades (4-1). Despite this rebalancing, current results still show slightly higher performance than in 2019, likely reflecting residual pandemic protections​.

Adjustments in the 2024 GCSE Exams

The 2024 GCSE results represent a move back to normality, with most pandemic-related exam adaptations, such as formula sheets, now removed. The shift towards traditional exam settings has seen minor changes in grade distributions, particularly for crucial benchmark grades. For instance, while the number of students achieving grade 4 has decreased, those achieving grade 5 have increased slightly, suggesting more students are pushing past the grade 4/5 boundary. This reflects the balance that examiners are trying to achieve to ensure fairness while maintaining rigorous standards​.

In 2024, Ofqual also instructed exam boards to apply more generous grading standards in specific subjects, notably French, German, and Computer Science. This decision aimed to address concerns about overly stringent grading in these areas and to encourage student participation.

GCSE Grade Boundaries in 2025

As of May 2025, there have not been any recent changes to how the grade boundaries are set. However, GCSE grade boundaries change every year. To find the grade boundaries for a specific subject and exam board, you will find them published on results day, or shortly thereafter, and can be found on the relevant exam board's website.

The Role of Exam Boards and Fairness in GCSE Results

Each year, exam boards work to ensure that grade boundaries reflect the difficulty of the papers and maintain fairness across different years. For instance, Ofqual guidelines require that higher-tier exams include questions targeting both top-end students (aiming for grades 9-7) and those aiming for mid-range grades (6-4). This balanced distribution of question difficulty helps create a fair assessment for all students. In addition, grade boundaries are carefully set after all marking is complete, ensuring that students aren't penalised for more difficult exams​

How Do GCSE Grades Affect Post-16 Choices?

The grades your child achieves at GCSE level will play a significant role in shaping their post-16 options. For students aiming to go to sixth form or college to study A-Levels, most institutions require a minimum of five GCSEs at Grades 4 or 5, including in key subjects like Maths and English.

Additionally, some schools and colleges may require higher grades, especially in the subjects a student wishes to pursue at A-Level. For example, a student wanting to study Maths at A-Level may need to achieve at least a Grade 6 or 7 in their GCSE Maths exam.

Students with lower GCSE grades can consider alternative qualifications like apprenticeships or vocational courses, which offer different pathways to employment or further education.
