Independent Study Proves Children's Literacy Initiative's Methodology Provides Significant Results

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.

CLI Annual Report 2022 - Teacher Impact Quote
With all the resources and coaching presented by my CLI coach, I was able to use different strategies and modalities to teach my students strategies to become fluent readers, and their comprehension enhanced. It has been an awesome experience to see my children blossom into reading, enhance their reading, and with guided reading lessons, close reading gaps.
