LightSail is the only literacy accelerator that combines all of the best books with in-text embedded assessments and real-time, actionable data to deliver industry-leading literacy gains.

LightSail is personalized to each student, ensuring that they are reading high-interest books right at, or above, their individual reading level. LightSail assesses students as they read, and adapts their libraries as they grow. Students using LightSail’s platform for just 30 minutes a day are seeing average gains of 2x “Ideal Lexile Growth.”
