# ClassLink SSO and Rostering with LitLab
> Set up ClassLink single sign-on with LitLab, sync your class roster, create assignments, and get students logged in through their ClassLink portal.
LitLab integrates with ClassLink for single sign-on and roster syncing. Once your district's ClassLink connection is set up, teachers can sync classes with one click and students sign in automatically from their ClassLink portal.
## Signing In
Teachers choose the **Sign in with ClassLink** option on the LitLab sign-in page.
Students sign in via their ClassLink portal.
## District Setup
ClassLink rostering requires a one-time setup between your district's IT team and LitLab:
Your district adds LitLab as an app in the ClassLink Admin Console.
Your district configures and enables a Roster Server connection for LitLab.
Your LitLab account team completes the connection on our side.
Once complete, teachers can sync their classes using the **Sync with ClassLink** button on their dashboard.
If you are a ClassLink IT admin, contact us at [ops@litlab.ai](mailto:ops@litlab.ai) to begin the RosterServer authorization.
Teachers can sign in with ClassLink before this setup is complete, but they won't be able to sync their classes or students until the RosterServer authorization is complete.
## Rostering Your Class
Once your district's ClassLink connection is live, follow these steps to import your classes and students.
From the LitLab sign-in page, click **Sign in with ClassLink**, or launch LitLab from your district's ClassLink portal.
From your teacher dashboard, click **Sync with ClassLink** to import your rostered classes and students.
If a student is added to your class in ClassLink after your first import, click **Sync with ClassLink** again from your dashboard, or open the class menu and pick **Re-sync roster**.
Archive ClassLink classes if you want them out of your active view.
## Creating an Assignment
Once your class is rostered, assign a decodable so students start reading right away.
From the dashboard, click **+ New assignment**, or click **Assign** on any decodable. See [Assigning Decodables](/practice/assigning-decodables#open-the-assignment-window) for the full walkthrough.
Choose your whole class, a small group, or individual students. Set recording on or off, and confirm the phonics skill.
Click **Assign**. The decodable appears on your students' pages the next time they log in.
For managing, reordering, or removing assignments after they're sent, see [Managing Assignments](/practice/managing-assignments).
## Getting Students Logged In
Students at ClassLink districts can sign in two ways, with no class code, username, or password required.
* **From the ClassLink portal.** Students click the LitLab icon inside their ClassLink launchpad. They're authenticated automatically and land on their personal page with their assigned decodables ready to read.
* **From the LitLab sign-in page.** Direct students to the **Sign in with ClassLink** button on the [LitLab student sign-in page](https://www.litlab.ai/auth/class-code).
If a ClassLink student can't find their name or their class after signing in, re-sync the roster from your class menu. If the student is still missing, confirm with your IT admin that the student is in the ClassLink roster shared with LitLab.
## Adding Another ClassLink Class
After you've rostered your first class, you can import additional ClassLink classes at any time without re-syncing everything.
Open your teacher dashboard.
Click the **Class** drop-down at the top of the dashboard to see your active and archived classes.
At the bottom of the drop-down, click **+ Import from ClassLink** to pick another rostered class to bring into LitLab.
