How on earth do the exam boards process all the grades?

[SparklesandGold]

Not a teacher, but given that schools had to use evidence to calculate grades for gcse and a level students this year and submit all that to exam boards, how on Earth do they process all that for thousands of students?

Did they send out the evidence (mocks, homeworks etc) to examiners for them to review instead of them marking exam papers or did a big computer system do it all?

Genuinely interested!

They checked a sample at Gcse and A level from each school.

Each school had to submit its policy / rationale explaining how they came up with the grades (for all subjects) then the boards requested samples (for some subjects).

They didn't! It would be an impossible task.

They took a small sample from schools and adjusted approx 1% of grades.

Basically, the big computer and data from schools as above.
