How to limit what board members can view
Asked by Farhan Kamal:

Hi I just recently started using Trello for my students. My Board setting is private. I invite students through a link. My problem. the students can view almost all the options as me like adding attachments, viewing power ups etc. Which I don't want.   

I have seen some public boards that are exactly what I want but I cant seem to configure that on my board. For example this card has no other option except for 1) Share 2) copy.

Adding observers to boards {#toc-hId--1350649415}
-------------------------------------------------

Teams that subscribe to [Trello Business Class](http://trello.com/business-class) can add "Observers" to boards within their team. Observers are board members that are able to view a board and the cards within the board, download card attachments, comment and vote on cards if that is enabled for the board, and export the board.

Observers are not able to move or edit cards, upload card attachments and Observers can't change board settings.

Because an Observer is a board member permission and not a membership *type* , a Business Class board admin can set both team members and Guests as an Observer on a board. There are no limits to how many Observers you can have on a board, and an Observer can be a billable team member or [Multi-Board Guest](https://help.trello.com/article/1123-multi-board-guests) or a non-billable Single-Board Guest. To understand if an Observer is billable, check out the page [How Billing Works with Trello Business Class](https://help.trello.com/article/855-how-billing-works-with-trello-business-class).

Add an observer {#toc-hId-1136863418}
-------------------------------------

To add someone to your board as an Observer, click "Invite" from the top of the board. Enter the member's username or email address. When you choose the person to add, the default choice is to add them as regular board members, but you can click on the down arrow to change that to "Add as Observers."

Change a member's permissions to Observer {#toc-hId--670591045}
---------------------------------------------------------------

To change a current board member's permissions to Observer, click their avatar from the Members section of the board menu, select "Change Permissions" and select "Observer". Please note that only team admins and board admins can change a board member's permissions.
