Without preassessment, it is difficult to determine what learning has occurred. Answers given on the end assessment may very well have been known if a preassessment had been given. Think of the learning that could have gone on during that time period! Preassessment makes differentiation possible; it is what makes differentiation defensible. Based on readiness, learning profile, and interests, preassessment helps determine appropriate content, process, product, and assessment for each child. Designed for the middle school educator, this session focuses on practical preassessment strategies complete with practice, preassessment samples, and student examples.
