LETRS: Making a Difference in Mississippi

When state of 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 short years, the results have been astonishing, and each year measures significant student literacy gains.

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 Times, Hanford asked the question and called out Mississippi’s impressive performance when the National Assessment of Educational Progress’ shared standardized test results showed fourth and eighth grade achievements in reading were made by Mississippi and the state made more progress than any other in the nation.

We are very proud to be partnered with Mississippi educators to improve literacy instruction with LETRS and ensure all teachers understand science of reading pedagogy.
