Kansas Reading Initiative (2014/15)

Lexia Core5 Reading -- Kansas Reading Initiative

Data compiled and analyzed by the Research Team (research@lexialearning.com)

The Kansas Reading Initiative (KRI) is a pilot program designed to improve reading outcomes in the state of KansasBased on a recent analysis, it was shown that when compared to Non-KRI schools, use of Core5 in KRI schools contributed to greater advances on DIBELS Next®, a commonly used progress-monitoring tool.

Sample Participants

This analysis included K-5th grade student data from three KRI schools and four Non-KRI schools. Students in the KRI schools used Lexia® Core5® Reading (Core5) for at least 24 weeks during the 2014-2015 school year.  KRI schools met the usage criteria required in the KRI program.  Non-KRI schools were selected because they showed a similar pattern of beginning-of-year scores on DIBELS Next as the KRI schools. There were 538 KRI and 1,474 Non-KRI students in the analysis.


Each school provided grade-level composite scores based on DIBELS Next Former goals.  Composite scores were used to categorize students as At/Above Benchmark or Below/Well Below Benchmark. Chi-square tests showed that differences in end-of-year Benchmark Status favored the KRI schools.  Of the 12 possible comparisons of KRI schools and Non-KRI schools (3 KRI X 4 Non-KRI), 10 (83%) resulted in significant differences favoring KRI schools.

Figure 1 presents changes in Benchmark Status on DIBELS Next for KRI and Non-KRI students. Data are aggregated across the three KRI schools and four Non-KRI schools.  KRI schools averaged a 15 percentage point increase in students categorized as At/Above Benchmark.  In contrast, Non-KRI school showed a smaller change (5 percentage point increase). Conversely, the percentage of students categorized as Below/Well Below decreased to a greater extent for KRI schools than Non-KRI schools.
