The strengths of the model are its generality, the fact that it provides…

Progress monitoring is a method of keeping track of children's academic development. Progress monitoring requires frequent data collection (i.e., weekly) with technically adequate measures, interpretation of the data at regular intervals, and changes to instruction based on the interpretation of child progress.
