CE2I participants are evaluated formally and informally throughout the program. Although students are given required tests, quizzes, written assignments, and projects throughout the program, they are not given a final grade or credit for their courses. Instead, written evaluations are used to encourage collaboration and mastery as desired academic behaviors. Upon arrival, every student is benchmarked on prior subject knowledge. At the midpoint of the program, each instructor gives a detailed evaluation of the student's performance (subject mastery) relative to the benchmark, along with specific recommendations and resources for improving mastery. The hope is that students will have time to implement these strategies and improve their academic performance before the final evaluations are given at the end of the program.
