Reading Plus Students Across all Tier Groups Achieved Significant Reading Proficiency Gains

All Tier Groups

Summary of Findings:

The results of this study show that students in all grade levels who engaged in Reading Plus instruction over the course of the 2018-2019 school year significantly increased their capacity to comprehend increasingly complex texts, developed their capacity to understand higher levels of general academic vocabulary, and improved their reading efficiency. 

These results show that students in all tier groups who engaged in the recommended amount of Reading Plus instruction over the course of the 2018-2019 school year significantly increased their capacity to comprehend increasingly complex texts, developed their capacity to understand higher levels of general academic vocabulary, and improved their reading efficiency. Students who completed more Reading Plus lessons achieved significantly larger gains than their peers who engaged in little or no Reading Plus practice. The results also showed that students who engaged in more Reading Plus instruction developed more reading confidence and increased their interest in reading. This in turn increases the likelihood that they will continue to use reading as a means to expand their knowledge, to be entertained, and to seek inspiration.

Study Design:

This report describes the reading progress achieved by Reading Plus students who were enrolled in grades 2 through 12 during the 2018-2019 school year.

Students Excluded Students for whom valid reading rates could not be calculated. Distribution of Students

  • Elementary School (Grades 2 through 5) n=46,007
  • Middle School (Grades 6 through 8) n=133,543
  • High School (Grades 9 through 12) n=79,590

Key Results:

Students who completed more Reading Plus lessons achieved significantly larger gains than their peers who engaged in little or no Reading Plus practice. The results also show that the students who engaged in more Reading Plus instruction developed more reading confidence and increased their interest in reading. This in turn increases the likelihood that they will continue to use reading as a means to expand their knowledge, to be entertained, and to seek inspiration.
