# Assign subdivisions to sessions

> Map each subdivision to a session so gymnasts know when and where they compete.

## Prerequisites

* [Create subdivisions](https://docs.gymart.org/competitions/create-subdivisions) or [create age groups](https://docs.gymart.org/competitions/create-age-groups) (which auto-create competitions with subdivisions)
* [Create a session](https://docs.gymart.org/scheduling/create-a-session)

## Steps

1. From the meet admin, go to **Scheduling** then **Sessions**.
2. Select the session you want to assign subdivisions to.
3. In the session's **Competition Assignments** section, choose which subdivisions compete in this session.
4. Select the **level**, then the **competition** (age group), then the **subdivision**.
5. Repeat for each subdivision you want in this session.
6. Save the session.

## How it works

Each session can include subdivisions from **multiple levels and competitions**. A Saturday AM session might include:

* Level 5, Ages 8-9, Subdivision A
* Level 5, Ages 10-11, Subdivision A
* Level 6, All Ages, Subdivision A

This flexibility lets you mix levels and age groups within a single session time block.

## Rules to keep in mind

* Each subdivision should be assigned to **exactly one session**. If a subdivision is not assigned, those gymnasts won't appear in any session schedule.
* A session can have **multiple subdivisions** from different competitions.
* All gymnasts within a subdivision compete in the **same session**.

## Example

Level 5 has two age groups, each with two subdivisions:

| Competition          | Subdivision | Assigned Session |
| -------------------- | ----------- | ---------------- |
| Level 5 - Ages 8-9   | Group A     | Saturday AM      |
| Level 5 - Ages 8-9   | Group B     | Saturday PM      |
| Level 5 - Ages 10-11 | Group A     | Sunday AM        |
| Level 5 - Ages 10-11 | Group B     | Sunday PM        |

## What's next

Once subdivisions are assigned to sessions:

* [Assign gymnasts to rotations](https://docs.gymart.org/scheduling/assign-gymnasts-to-rotations) within each session
* [Configure rotations](https://docs.gymart.org/scheduling/configure-rotations) for apparatus order
* [Set the session timeline](https://docs.gymart.org/scheduling/set-session-timeline) for warmup, competition, and awards

Plan session assignments before opening registration if possible. It helps coaches understand the schedule. If you add gymnasts to a subdivision after assignment, they automatically appear in the assigned session. You can reassign subdivisions to different sessions at any time before competition.
