Independently Validated Results

CLI’s work has been validated by prestigious independent organizations and has garnered national attention for its ability to raise student literacy scores while building schools’ internal capacities for teacher professional development.

Results from a three-year, randomized control-group study of CLI’s i3 project in four cities by American Institutes for Research, showed that:

  • Kindergarten and second grade students in CLI schools scored significantly higher on standardized early reading tests than students whose teachers were not exposed to CLI.
  • CLI had a significant positive impact on the quality of teachers’ literacy instruction in both kindergarten and first grade classrooms.
