From EOGs and Milestones to NWEA MAP, FAST, and SBAC, ReadTheory helps students sharpen the exact skills they’ll need—like main idea, inference, and vocabulary in context—while providing teachers with easy-to-read growth data and Lexile trends.
4. No Cost, No Catch
ReadTheory is 100% free for teachers and students. No trial periods. No paywalls. Just effective, engaging reading practice with the data tools you need to drive instruction.
