CLI’s i3 evaluation consisted of a randomized control trial conducted in 78 high-poverty schools in four urban school districts using the PAR, GRADE and ELLCO assessment tools.
The impact evaluation was designed to evaluate the effect of the CLI model classroom coaching and professional development program on kindergarten through second-grade teachers’ classroom environment and literacy instruction, as well as the effect of the CLI program on student literacy achievement.
CLI’s program was implemented with high fidelity during each year of the study. A large service contrast was observed in the amount and type of professional development and coaching received by treatment and comparison teachers, with treatment teachers reporting that they had received substantially more literacy-focused professional development.
In 2010, Children’s Literacy Initiative partnered with the American Institutes for Research (AIR) to evaluate the impact of CLI’s Model Classroom Program.
Year 2 findings demonstrate that Kindergartners in CLI schools score significantly higher on standardized early reading tests than students whose teachers are not exposed to CLI, and that CLI had a significant positive impact on the quality of teachers’ literacy instruction in both Kindergarten and 1st grade classrooms. The exceptionally high level of rigor of this study makes these results stand out among other less rigorous claims put out by other professional development organizations.
