Measure: InSight assessment

Publication: Reading Plus Brief, 2020

Authors: Reading Plus Research

Summary of Findings:

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. The focus of the report is on students who completed the Reading Plus InSight silent reading assessment on at least two occasions, once near the start of the school year and again during the spring, so that growth over the school year could be measured.

Key Results:

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. 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.
