The ‘Leaving Year group’ field should be available in the Student Manager – Alumni API. We need this to be able to perform an historical calculation of which year group a student was in at a specific date, working backwards from their leaving year group and leaving date. The odd thing is that this field is available in the Student Manager REST API, but that API does not return alumni students, only current students, so the field is never populated. Actually, If this API returned ‘ALL Students’, including leavers, that would solve the problem as we could filter the leavers out separately. See further notes attached.
