PRS OVERVIEW

Your PRS RF Clicker is part of the InterWrite PRS
student response system. You use this RF Clicker in
your classes to respond electronically to questions.
In the typical classroom scenario, you login to, or

During the join process, your Student ID, your
unique identifier, is transmitted to the PRS software
via the RF Receiver. Each time you send a
Response to a Question, your Student ID is
attached to your Response, ensuring each answer
you send is attributed to you. Your Responses are
recorded electronically, and can be scored and
stored in an electronic Gradebook.
