My 1st graders completely soared. I have a little group of 2nd graders that are real strugglers. Their scores are the lowest of the low but they made gains and understood concepts. I know if I would have been teaching anything else, they would not have progressed as they did. It’s amazing.

I love sharing the magic you all worked on with our Summer Academy students. Of the students who attended 70% showed growth. Of those 70%, 67% of them made 2 years growth, 25 % made 1.5 years growth, and the rest showed 1 year growth!
