A data set from an urban Midwestern school district was mined to explore how the technology-based reading enrichment known as Mindplay Virtual Reading Coach (MVRC) affects children's performance on the English Language Arts (ELA) Standards state-wide assessment (N = 6098 students from Grades 3 to 9). ELA data from two times points were available, approximately one year apart. ELA data were correlated with various data points obtained from MVRC, including the benchmark assessment administered at the beginning and at the end of the year. Results revealed large correlations across grade levels for the MVRC Composite score obtained from the MVRC Universal Screener, 0.40 < r < 0.74. Results also revealed that the amount of MVRC exposure was linearly related to an increase in ELA performance at the end of the year, largely independent of grade level and students' initial reading competence. Girls and boys benefited equally from MVRC exposure, as did children from different ethnicities. The most prevalent factor in predicting the ELA-MVRC relation was the type of school, with MVRC exposure having the highest benefits in non-failing elementary schools, compared to high schools.
