Class Status Report for teacher or principal

This is an example of a first grade classroom report for December.

The teacher can immediately see which of her students are at most risk for not being at grade level at the end of the year, and can use this report to group students for targeted instruction and support

Student Progress Report for teacher or principal

This report shows the progress of a third grade student in becoming a fluent and accurate reader in third grade. At the beginning of the year, the student was classified as high risk on this measure, but the student received excellent intervention, and by the end of the year, he was performing in the low risk range.
