Literacy Professional Learning That Gets Results

When Mississippi officials provided funding to train educators in the science of reading, Voyager Sopris Learning® partnered with them to deliver LETRS literacy professional development. In four years, the results have been astonishing. Each year measures significant student literacy gains. Statewide LETRS implementation made Mississippi No. 1!

Mississippi Outperforms All

With LETRS, Mississippi is the only state to increase scores on National Assessment of Educational Progress.

Senior education correspondent Emily Hanford may have said it best when she asked, “What’s up in Mississippi?” In her op-ed about the science of teaching reading for The New York TimesThere is a Right Way to Teach Reading, and Mississippi Knows It.

Mississippi proves that LETRS transforms classrooms and results in measurable, statistical improvements. Mississippi is only one example—please ask us about other case studies and testimonials.
