# Slot Capacity Updates
> Changes to room and seat allocations within a capacity slot are synced to partner organizations, keeping available capacity accurate on both sides.
## Overview
Each planning slot in your center is backed by a **seat allocation** — the specific rooms and seats assigned to that time window. When you add rooms to a slot, remove rooms, or adjust which seats are included, those changes sync to your partner organizations so their capacity view stays accurate.
***
## What slot capacity data is synced
| Element | Description |
| --------------------- | -------------------------------------------------------- |
| **Rooms in the slot** | Which rooms are assigned to a specific occurrence |
| **Total capacity** | Aggregate seat count across all rooms in the slot |
| **Individual seats** | Seat identifiers available within each room for the slot |
| **Seat status** | Whether a seat is active and available for assignment |
**Candidate and proctor assignments are not synced.** The "Candidate" and "Proctor" columns in your seat allocation view show data specific to your organization. The partner organization manages their own assignments independently. See [What is Not Synced](/center-and-proctor-administration/center-federation/what-is-not-synced).
***
## Adding a room to a slot
If you need to expand capacity for a specific slot occurrence, you can add an additional room to it:
From the **Capacity** tab, click on the slot time (for example, "10 AM – 12 PM") to open the seat allocation view for that occurrence.
Click the **+ Add room** button in the top-right corner of the seat allocation view.
Choose the room to add to this slot. Only rooms configured in the center and assigned to the relevant workflow step are available.
Click **Confirm**. The room and its seats are added to the slot. The updated capacity is synced to partner organizations automatically.

## Removing a room from a slot
From the **Capacity** tab, click on the slot time to open the seat allocation view.
Click the **trash icon** next to the room row header (for example, "LRW Room — Friday, May 1, 2026") to remove that room from this occurrence.
Confirm the action. The room is removed from the slot and the partner organization's capacity for that slot is updated accordingly.
Removing a room from a slot reduces the total capacity visible to the partner organization. If the partner has already assigned candidates to seats in that room, those assignments are not automatically cleared. Coordinate with your partner before reducing slot capacity when bookings exist.
***
## Managing individual seats within a slot
From the seat allocation view, you can:
* **View all seats** — see each seat identifier, its status (Available, Occupied), and any assigned candidate or proctor in your organization
* **Remove a seat** — click the trash icon next to a seat to remove it from the slot for this occurrence
* **Add a seat** — capacity is determined by the room's configured seats; add seats to the room (see [Rooms & Seat Map](/center-and-proctor-administration/center-federation/managing-rooms-and-seats)) to make them available in slots
Seat-level changes sync to the partner organization as part of the slot's configuration.

## Effect on partner organization's capacity view
After a slot capacity update, the partner organization's **Capacity** tab reflects:
| Your action | Partner organization sees |
| ------------------------- | ----------------------------------------- |
| Add a room to a slot | Room added; total capacity increases |
| Remove a room from a slot | Room removed; total capacity decreases |
| Add seats to a room | More seats available in that room's slot |
| Remove seats from a room | Fewer seats available in that room's slot |

## Frequently asked questions
Yes. Once the sync completes (typically within seconds), the additional room and its seats appear as available in the partner organization's seat allocation view, and candidates can be booked into them.
Reducing capacity (removing rooms or seats) does not automatically cancel bookings. Bookings that existed before the reduction remain assigned. Consult with the partner organization to manage any over-allocation if needed.
Yes. You can open any individual occurrence (by clicking its time in the Capacity tab) and add or remove rooms just for that date, without affecting other occurrences in the series.
The capacity columns in both organizations should match after a completed sync. If there is a discrepancy, wait a few seconds for the sync to complete. If the mismatch persists, contact your platform administrator.
