# Attendance

chestnut.tools supports two attendance modes: **daily** (school-wide check-in/check-out) and **per-course** (attendance tied to a specific class).

## Daily Attendance

### Starting a Session

1. Go to **Attendance → Daily**.
2. Choose **Check-In** or **Check-Out** from the segmented control.
3. (Optional) Enable **PIN** and a four-digit code is generated automatically. You can display it full-screen for students to read from a distance.
4. Click **Start** to open the session.

While the session is active, the table updates in real time as students check in or out.

### Ending a Session

Click **Stop** to close the session. The records are saved and will appear in the attendance history for that date.

### Reviewing Past Attendance

Use the date picker at the top of the Daily Attendance page to navigate to any past date and see who checked in or out.

### Tardiness

A student is automatically marked **tardy** if they check in more than 10 minutes after the session start time.

### Filters

The attendance table can be filtered by:

* Student name (text search)
* Presence status (present, absent, tardy)
* Role
* Staff member

***

## Per-Course Attendance

Go to **Attendance → Per Course** to view attendance records tied to individual courses. Select a course from the list to see which students were present, absent, or tardy for each session.

***

## Per-Student Attendance

Go to **Attendance → Per Student** to view the full attendance history for a single student across all courses and daily sessions.

Use the search bar to find a student by name.

***

## Editing Attendance Records

Staff with the `manage_attendance` permission can edit any attendance record directly in the table. Click a cell to update a student's presence status.
