Summary of Findings
Students who received Reading Horizons instruction scored higher on tests of reading skills as compared to students at the school and the district who did not receive Reading Horizons instruction. Additionally, more than 90% of students who received Reading Horizons instruction scored average or above when tested in five areas related to reading.
Two first grade teachers at one school were selected to include Reading Horizons instruction in their classrooms. To strengthen the validity of the results and to increase opportunities to generalize outcomes to other classrooms, administrators intentionally chose one teacher who was very good and one teacher who was average.
Reading Horizons direct instruction materials.
Outcomes were gathered for students in the two first grade classrooms and compared to scores of students at Atkin Elementary School who did not participate in Reading Horizons instruction. Scores were also compared to scores of students in the district who were also not receiving Reading Horizons instruction.
