A Level grades explained: Everything you need to know

A Levels play a key role in post-16 education and offer a well-established path to university and higher education. 

But since 2015, reforms have made them tougher and more aligned with university expectations.

Students received the first reformed AS Level results in 2016, followed by updated A Level grades in 2017.

Now, in 2025, what do these changes mean for pupils today?

This guide helps both students and their parents understand how modern A Level grades work with the national curriculum, what’s changed and what it means for future success.

What’s changed in the A Level system?

In the past, A Levels were modular, meaning students took exams throughout the course, often with opportunities to retake units to improve their grades. 

Under the reformed system, this is not the case.

Now, both AS and A Level grades are linear. This means students are assessed at the end of the course, not in stages. 

AS exams are typically sat after one year of study, while A Levels are taken at the end of two years.

The most important changes are:

• No more modular units or January exams
  
• Assessment happens only at the end of the course
  
• AS and A Level qualifications are “decoupled”, meaning AS results do not contribute to the final A Level grade
  
• Greater emphasis on final exams, with non-exam assessments only used where essential (e.g. practical skills or creative work)

Decoupling of AS and A Levels

Before the reform, students would often take AS Levels in Year 12 and ‘top them up’ to full A Levels in Year 13, with AS results contributing 50% to the final grade.

Now, AS and A Levels grades are entirely separate qualifications. 

While schools may still choose to offer AS courses alongside the first year of A Level study, the results from AS exams no longer count toward the full A Level. 

A student can still progress to A Level without taking an AS exam, or they can sit the AS purely as a standalone qualification.

This change gives schools more flexibility and allows students to focus more deeply on their chosen subjects without being limited by early exam performance.

How are pupils assessed in the new A Level structure?

One of the biggest reforms is the move away from modular testing and toward end-of-course examinations.

Most A Level subjects rely entirely on final written exams for assessment.

Non-exam assessments (NEAs), like coursework, appear only when exams can’t measure certain skills.

For example, some English courses use coursework to show understanding, and Art requires a portfolio built over time.

This approach puts the focus on students’ understanding of the entire subject at the end of the course and encourages deeper learning.

How is the new A Level content different?

As part of the reform, the government has updated and improved the subject content of A Levels.

One of the major goals of the overhaul was to make A Levels more relevant and academically demanding.

Key changes include:

• More input from universities in designing the curriculum
• Content that better prepares students for higher education and real-world academic challenges
• A push for greater clarity and consistency in what’s taught and assessed across exam boards

This means that students in 2025 are studying more focused and coherent subject material, designed to reflect the expectations of leading universities.

Why were these changes introduced?

The government reformed AS and A Levels as part of a broader effort to raise academic standards and clarify qualifications.

Their goal was to keep A Levels internationally competitive and ensure grades accurately reflected each student’s ability and understanding.

The new system cut down on “gaming” through modular retakes and gave universities greater confidence in A Level results as indicators of student potential.

By placing more weight on final exams and giving schools more control over course planning, the reformed A Levels aim to balance challenge with fairness.

How are A Levels different in Wales, Northern Ireland and Scotland?

Wales

In Wales, A Levels are still widely used, but the Welsh government chose not to fully adopt the English reforms. This means:

• AS Levels in Wales still count toward the final A Level grade, unlike in England where they no longer do
• The modular structure remains in place, allowing for assessment in units and January exams in some subjects
• Although content has been updated, Welsh exam boards follow different guidelines from Ofqual, the English regulator

Students in Wales still receive A to E grades* and take qualifications managed primarily by the WJEC exam board.

Northern Ireland

Northern Ireland offers a hybrid model, giving schools the option to follow either the reformed A Levels from England or stick with the local CCEA qualifications. Key points include:

• The CCEA A Levels remain modular, with AS Levels counting toward the full A Level grade
• Northern Ireland retained the traditional January and summer exam windows
• Like Wales, grading still follows the A to E scale*
• However, schools that use English exam boards (like AQA or Edexcel) will follow England’s linear, decoupled A Level structure

Scotland

Scotland does not use A Levels at all. Instead, it follows a completely different qualification system:

• Students typically take Highers and Advanced Highers, with the Scottish Qualifications Authority (SQA) overseeing them
• Students usually take Highers in S5 (ages 16–17) and Advanced Highers in S6
• Unlike A Levels, Highers are one-year courses, though Advanced Highers offer a deeper level of study closer to A Level standard

Universities across the UK recognise Scottish Highers and Advanced Highers as equivalent to A Levels when making admissions decisions.

What does this mean for pupils in 2025?

If you are currently studying or preparing to study A Levels in 2025, here’s a checklist of everything you need to know:

• Your A Level grades will come entirely from your final exams at the end of two years
• Taking the AS Level is optional and won’t affect your A Level grade
• Most of your subjects will be exam-heavy, so consistent revision and a deep understanding of the full syllabus are essential.
• You’ll study subject content shaped to meet university expectations and match modern academic standards

A Levels rank among the most demanding qualifications students face in their academic journey.

With intense final exams, deeper subject content and a fast-paced curriculum, even the most capable students can quickly feel overwhelmed.
