How do I make a left or inactive student active again (re-admit them) when Manage Students does not show them?

There is no separate "activate" button. A student becomes active again the moment their Current Status is set back to Currently Enrolled on the update form. The only trick is finding them: Admissions › Manage Students lists Currently Enrolled students only, so a child marked Left, Graduated, Expelled or Suspended is not there — which is why it looks like there is no option.

Steps

1. Open Extras › All Students — it lists students of every status
2. Find the child with the column filters (student name, admission number, father's name) — or press the grid settings gear, switch on the Current Status column and filter it to Left
3. Click the cog at the end of the row → Update
4. Under Office Information, change Current Status to Currently Enrolled; the Date of Leaving box disappears
5. Check the campus, class, section and fee plan are the ones they are joining now
6. Press Update and Go Back

The child is back in Manage Students, attendance and challan generation straight away. Their old admission number, roll number, fee history and results stay attached — nothing is created twice.

To make many students active at once

Select them in All Students, press Bulk Edit, choose Currently Enrolled under Select Status, then Update.

Good to know

• The old Date of Leaving stays on the record after the child is active again (the Leaving Date column in All Students still shows it). The status is what counts — the child is no longer in the Inactive Student Report
• Both the Left change and the active again change are recorded in User Logging as Critical and in the child's Change Log, with the person and the time
• The Update button stays grey until every red-labelled field on the form is filled — Fee Plan is one of them, so a returning child needs a fee plan chosen
• If your school has set seat limits under Core › Admission Capacity and switched the hold on, making a child active into a class that is already full is saved but held: the message says the student is waiting for approval before they are counted, and they appear in Admissions › Admission Approvals. Schools with no capacity limits see no change
• The Parents App pulls enrolled children only, so the child shows there again the next time the parent signs in
• Do not add the child again as a new admission — that creates a duplicate record with a second admission number and its own fee plan
