Validation Study of Keystone Book Assessments

The study investigated the validity of the Keystone Book Assessments for assessing students’ reading gains on texts of graded difficulty. A total of 47 reading specialists from 24 schools across 9 states administered the Keystone Assessments and the Slosson Oral Reading Test to 800 K-2 children in January and in May. The correlation results from pre-and post-testing provide evidence that the Keystone texts are a valid tool for assessing and monitoring students’ reading gains. The study will be submitted for publication.
