Is it possible to disable the "EDIT" tab for logged in users in MediaWiki?

The MediaWiki is log in only so the public and visitors cannot see it. However, I only want a few logged in users to have ability to EDIT, and every other logged in user not be able to EDIT but just to read and view the pages.

Can that be achieved?
