How do I limit my students to see only me in a Zoom meeting?

There is a function called Focus Mode which is designed specifically for situations like yours. Focus Mode aims to let participants (students) only see the Teacher (Host) and not each other (participants seeing other participants). The feature needs to be enabled first so the option becomes accessible in the Zoom client.

To Enable Focus Mode

1. Sign in to the Zoom web portal as an admin with the privilege to edit account settings.
2. In the navigation panel, click Account Management then Account Settings.
3. Click the Meeting tab.
4. Under In Meeting (Advanced), click the Focus Mode toggle to enable or disable it.
5. If a verification dialog displays, click Enable or Disable to verify the change.
   Note: If the option is grayed out, it has been locked at the account level and needs to be changed at that level.
6. (Optional) If you want to make this setting mandatory for all users in your account, click the lock icon, and then click Lock to confirm the setting.

1. Start a meeting as the host or co-host.
2. Click More on the meeting toolbar.
3. Click Start Focus Mode.
4. Click Start to confirm or the Don't ask me again check box to skip this confirmation going forward.
5. When Focus mode begins, you and the participants are notified with a banner along the top of the video window. Additionally, the focus mode icon is always visible in the top-left corner of the video window, next to the encryption icon, while focus mode is active.
