| Grade | Minimum mark | Mark range | Minimum % | Students |

Edit a minimum mark to fine-tune the boundaries. The lowest grade catches everything below the next boundary, so its starting mark is fixed at 0 when a maximum mark is supplied, or at the lowest observed score when it is not.

About Grade Boundary Calculator
This grade boundary calculator helps teachers turn student marks into an editable set of assessment grades. Paste two columns from Excel containing names and scores, enter one score per line, or use a plain list of marks. An optional maximum mark enables percentages alongside raw scores. Choose a foundation, higher or full-range grading scheme, with or without grade 0.
Generate suggested boundaries using a chosen peak grade, an automatic estimate from cohort attainment, or a comparative profile. The calculator uses the selected proportions and percentiles of the supplied marks to suggest minimum scores. Automatic mode uses an expected median grade when supplied; otherwise it uses the median percentage if a maximum mark is available, or the middle available grade as a fallback.
After generating results, edit minimum marks to apply your own teacher assessment judgement. Student grades and the cohort distribution update as boundaries change. Copy boundaries or student results into a spreadsheet, or download a CSV. Custom distribution profiles can be saved in this browser for later assessments. Review input warnings and grade ranges before using the output.
Are these official GCSE grade boundaries?
No. The built-in GCSE-style profiles are illustrative, and generated boundaries are cohort-relative suggestions. They are not official exam-board boundaries. Use the published boundaries for the relevant examination when official grades are required.
Does this upload student data?
Names, marks and grade calculations are processed in your browser. This calculator does not upload them to a server. Downloaded CSV files and copied results can contain student information, so store and share those outputs appropriately.
