If all your school's exam entries are up to date then importing exam results is a straight forward process.
Locate the relevant results files from the A2C Migration App or from the Exam Board. These will be EDI files starting with an 'R' and with a file extension of '.Xyy' where yy is a two digit number.
Go to Admin > Import and press the Choose File button then upload your locally saved results file.
You will then see confirmation of the results that have/haven't loaded.
Check your results at Office > DfE Returns > Exam Results.
Print out your results, pupil by pupil, using the Exam Results Card template in Office > Office Reports & Print-outs > Multi-print.
