This 38-page report examines the literacy performance of K-3 students receiving the T3 Teach Plus intervention prior to implementation (2016-17) and two years after implementation (2018-19). It also compares the performance of students in T3 schools to that of students in matched comparison schools. Overall, the six measures of early literacy tell a nuanced story of the T3 program and the performance of K-3 students attending T3 schools and comparison schools in 2016-17 and 2018-19. One metric (minimum growth) showed students attending T3 schools outperforming students in comparison schools, three metrics (NPR, SGP, reading on grade level) showed that students in comparison schools were outpacing students in T3 schools, and two metrics (change in number of correct responses, ROI) found no differences between the two school types during the 2018-19 year.
