CommonLit was shown to accelerate learning

CommonLit has been shown to accelerate learning for students. In a large scale, nationwide study (n=113K) conducted in collaboration with Mathematica, students with higher levels of exposure to CommonLit 360 saw 2.1 months of additional learning.

CommonLit was shown to significantly increase student engagement and cultural awareness by 2x

The Mathematica study also found that students in CommonLit classrooms were more likely to report that class was engaging, interesting, and kept their attention. They were also more likely to say they felt proud of their background and had the chance to learn about other cultures compared to students in classes that did not use CommonLit.

CommonLit earned ESSA Tier III “Promising Evidence” certification

After completing the Mathematica study, CommonLit was awarded  ESSA Tier III certification for the effectiveness of its program. As of 2022-2023, only 4 out of the 100 of the most accessed EdTech products have earned this badge. Because CommonLit has earned this distinction, districts can use additional ESSER funding to bring our full instructional program to their schools.
