School year end is a simple 3 step process on Pupil Asset:
Sure, you might need to call another school to pester them into sending you their children. We're certain some of your parent's emails addresses will be wrong. But when it comes to rolling over pupils and tweaking your new auto-populated calendar, we're quite certain that PupilAsset's End of Year Process will be the breath of fresh air you've been craving.
UK DfE Census Returns are similarly pain-free too.
