The Delton Silent Reading Test, Forms A and B, was developed as an alternate test for the Schonell Silent Reading Test which is currently used for screening the reading comprehension of special students. The aim of the Delton Silent Reading Test is to achieve greater consistency in mid-year and mid-program assessments for special students who were originally assessed with the Schonell Silent Reading Test. This study reports the development of the Delton Silent Reading Test and the validation process undertaken to determine the equivalence of content, readability levels, comprehension strategies, questioning strategies and student test scores on the Delton and Schonell tests. Results indicate that there is no significant difference between matched test items on the Delton and Schonell Silent Reading Tests for item content, readability levels and reading and questioning strategies. Results from correlations of student test scores indicated that test scores did not differ significantly. (r=.93,p<.000001) Results of correlations of teacher ratings of students' reading ability and student achievement on the Schonell Silent Reading Tests were inconsistent.(r=.76,r=-.09) / Graduation date: 1994
