Grade Inflation Impact Calculator
See what grade your percentage would earn in any year from 2015 to 2024, and understand how grade inflation affects your result.
How This Calculator Works
Grade inflation happens when the percentage you need to achieve a specific grade decreases over time, or when more students receive top grades in a given year. This calculator uses historical grade boundary data and year-on-year inflation estimates to show what grade your percentage would earn in any year from 2015 to 2024.
Effective Boundary = Typical Boundary + Year Offset
// Step 2: Look up grade with adjusted boundaries
Grade = Adjusted Scale lookup(Your %)
// Step 3: Compare across years
Grade in Year A vs Grade in Year B = Difference in grade bands
// Example: 72% in 2023 vs 2019
2023: Boundaries slightly lower post-pandemic = Grade 7
2019: Pre-pandemic normal boundaries = Grade 7 (same)
2021: TAG year, inflated = Grade 8
UK Grade Inflation: What Actually Happened
Between 2019 and 2024, the proportion of students receiving top grades in both GCSE and A Level changed dramatically. The COVID years (2020-2021) were the most extreme, but the return to pre-pandemic standards has been gradual rather than immediate.
The COVID spike (2020-2021)
In 2020 and 2021, exams were cancelled. Centre-Assessed Grades (2020) and Teacher-Assessed Grades (2021) replaced written exams. The result was a significant jump in top grades. In 2021, 44.8% of A Level entries were awarded an A or A*, compared to 25.5% in 2019. At GCSE, grade 7 and above rose from 20.6% to 28.9% in the same period.
The return to normality (2022-2023)
Ofqual announced a managed transition back to pre-pandemic grade distributions. In 2022, results were set midway between 2019 and 2021 levels. In 2023, they moved further back toward 2019. By 2024, most subjects returned to approximately 2019 levels, though the exact boundaries still varied by subject and cohort.
Why it matters for students
A student who sat their A Levels in 2021 and received an A had a lower bar to clear than a student who sat the same exam in 2018. This does not mean 2021 students worked less hard; it means the grading system was temporarily easier. Employers, universities, and admissions tutors are generally aware of this context, and some explicitly adjust their assessment of grades from those years.
Table of Truth: How Grade Boundaries Shifted Year by Year
The table below shows the approximate percentage of A Level students receiving A or A* in each year, based on published national statistics.
| Year | A Level A/A* rate | GCSE Grade 7+ rate | Notes |
|---|---|---|---|
| 2015 | 25.3% | 19.9% | Pre-9-1 reform (GCSE) |
| 2016 | 25.8% | 20.5% | Normal year |
| 2017 | 26.3% | 20.6% | 9-1 GCSE introduced (pilot) |
| 2018 | 26.2% | 20.5% | Normal year |
| 2019 | 25.5% | 20.6% | Last pre-pandemic normal year |
| 2020 | 38.6% | 26.2% | CAGs (Centre-Assessed Grades) |
| 2021 | 44.8% | 28.9% | TAGs (Teacher-Assessed Grades) |
| 2022 | 36.4% | 26.3% | Managed transition; midway return |
| 2023 | 27.2% | 22.5% | Further return toward 2019 levels |
| 2024 | 26.0% | 21.3% | Near-normal; close to 2019 |

Does Grade Inflation Make Your Result Worth Less?
This is the uncomfortable question most students want answered. The short answer is: it depends on what you are using the grade for.
For university admissions
UK universities are aware of the 2020 and 2021 grade distributions. Many admissions teams adjusted their offers during those years to account for inflated grades, setting higher conditional offers or looking more carefully at predicted grades from normal years. By 2024, offers largely returned to 2019 norms. A 2021 grade is not necessarily devalued in the eyes of admissions staff, but it is contextualised differently than a 2019 grade.
For employers
Most graduate employers who ask for A Level grades as a screening criterion use them as a blunt filter rather than a nuanced signal. A 2021 student with an A is unlikely to be explicitly penalised. However, employers who care deeply about academic credentials (law, finance, competitive graduate schemes) may informally weight 2019 results more heavily.
For your own self-assessment
This is where the calculator is most useful. If you scored 72% in 2021 and received an A, knowing that the same 72% might have been a B in 2019 gives you an honest signal of where your knowledge sat relative to the historical baseline. That is useful for planning revision, deciding whether to resit, or understanding the gap between your grade and your actual mastery.
