The Early Interactive Reading Software Program encourages literacy growth and achievement in students in grades K-3. The program addresses early reading through the use of computer-based literacy software which provides individualized instruction designed to supplement students' classroom learning. During the 2019-2020 school year, these software programs were used in 139 local education agencies (LEAs) and by approximately 150,169 students. The schools use the software to build literacy skills for all students in kindergarten and first grade, as well as for intervention with students in second and third grade. The evaluation studied two aspects of the program: (1) student's use of the program during the first half of the school year ("program implementation"); and, (2) the effects the program had on increasing students' literacy achievement ("program impacts"), as measured by student's middle-of-year test scores, for all software programs combined. The 2019-2020 evaluation methods were adapted in response to the COVID-19 pandemic, which resulted in soft school closures and potentially shortened students' program exposure. The computer-based software programs were designed to be implemented across a full academic year. This report depicts program impacts at mid-year, before students received the full program. The evaluation was not designed to replace a full year-long study of program implementation and its impact on student learning, but the results can be used as a touchstone for gauging mid-year progress.
