Contact the ACT at the ACT Education contact link (see Resources). You will need to fill out your name, your location and title and the name of your institution. You have to contact the ACT so they can send you an application to become an ACT administrator.
Fill out the application that the ACT sends you. You will need to include the type of educational system you have or are a member of. The ACT will need to approve your application. Once the ACT has approved your application, they will give you permission to set up a testing center.
Set up your ACT testing center according to ACT guidelines. There are requirements that you will have to meet in order to make sure the testing center is set up correctly. For instance, you will need to have security measures in place, and you will need computers that are securely blocked so users will have access only to the test and nothing else. The ACT will then send you the software you need to set up the ACT tests for yourself.
