On the first day of a unit, students arrive and complete a Readiness Assessment Test (RAT). This is an approximately 12 multiple-choice question quiz to see if students have successfully understood the reading and homework. Here is an example RAT for Unit 3 – Forces and from Spring 2016. Students take this RAT individually. Once everyone on a team is complete, then they take the same RAT as a team on a IF-AT card. This experience provides valuable immediate feedback for students. While they are taking the team portion, students write down what they thought was most difficult on scraps of paper and place them in cups on each table. These comments, as well as the grades on the team portions, are used for some just-in-time lecture on the most difficult topics.
