Marking a class

Open the classroom and switch to Attendance. The page shows today's roll call by default — every student in the class as a row, with a tap target for present/absent.

Tap a row to toggle present (filled) or absent (outlined). The change is persisted instantly via POST /api/classrooms/[id]/attendance — you don't need to click save.

Mass-mark first, edit second

Click Mark all present, then tap individual rows to mark absentees. For most classes this is the fastest workflow — fewer than ten taps for a class of 40.

Marking a different date

Need to backfill from a class you forgot to mark? Use the date picker at the top of the page. Attendance is uniquely keyed by (userId, classroomId, date), so you can re-edit any past date without creating duplicate rows.

Batch attendance

For institutions that take attendance via a paper sheet or external system, the batch endpoint accepts a list of records:

POST /api/classrooms/:id/attendance/batch
{
  "date": "2025-09-12",
  "records": [
    { "userId": "user_abc", "isPresent": true },
    { "userId": "user_def", "isPresent": false }
  ]
}

Records are upserted, so the endpoint is safe to retry.

Per-student history

Click any student's name from the roll call to open their attendance history. The view shows every recorded date, the cumulative attendance percentage, and a sparkline of the trailing four weeks — useful for flagging patterns before they become problems.

Analytics and exports

The classroom Analytics tab includes:

Class-wide attendance rate per week.
Distribution of student attendance percentages.
A list of students below the institutional threshold (75% by default).

Each chart can be exported as a CSV for institutional reporting.

Things to know

No retroactive deletion. Marking someone absent that you previously marked present updates the row in place — there's no audit log.
Removed students keep their history. Removing a student from the classroom doesn't delete their attendance.
Notifications are off by default. Toggle Notify on absence in classroom settings if you want students to get an email when they're marked absent.
