About this Research

About This Research

This case study examined how Raz-Kids use impacted developmental reading scores in a classroom of first-grade students from a school serving economically disadvantaged families. The assessment used in the study (Developmental Reading Assessment) measures a variety of literacy skills including phonics, alphabetic principles, comprehension, and vocabulary.

Main Findings

Through the course of the Raz-Kids implementation, DRA (Developmental Reading Assessment) scores for the classroom increased from an average level of 4 to an average level of 16.


Participants were one teacher and 22 first-grade students in a school with a high proportion of economically disadvantaged students.

Study Design and Procedures

This case study compared data for the same group of students before and after the Raz-Kids implementation, which took place in the 2012–2013 school year. The DRA was used as pre- and posttest. During implementation, students used Raz-Kids during their reading block and were also encouraged to use the program at home.
