The present evaluation study sought to determine how LightSail is implemented within schools in three public school districts, Evergreen Public Schools (EPS), Denver Public Schools (DPS), and Oakland Unified School District (OUSD). Case studies conducted in a subsample of schools within the three districts included classroom observations, interviews, and focus groups. In addition, a survey was administered to teachers and students in two of the districts and usage data were collected from all three districts. Teachers, principals, coaches, and students found great value in the LightSail experience. Students responded enthusiastically to the opportunity to express themselves through self-selection of texts and the option to read without interruption for a period of time.
