Improving youth literacy by providing students with digital access to perfectly suited texts and accompanying assessments.

Children in the United States who are unable to read proficiently by third grade are four times more likely to drop out of school in later years. LightSail is dedicated to solving the most complex problems in K-12 literacy. Designed by teachers and influenced by students in K-12 schools, LightSail's personalized reading platform helps all students become competent readers. Every child using the platform not only has free access to thousands of fiction and nonfiction texts, but will be reading books that are suited to their reading level. Students choose books from the digital library, complete embedded assessments as they read, and engage in real-time dialogue with their teachers, facilitating reading advancement. Students reading 25 minutes a day on LightSail are seeing two or more years of Lexile growth in a single year. LightSail, now available in both English and Spanish, has been recognized by Forbes, EdSurge, and Common Sense Media.
