Comparison of Flesch readability scores with a test of reading comprehension

Abstract

101 high school seniors, who had taken the Diagnostic Reading Test, read ten 100-word passages judged to be of equal interest but varied systematically in Reading Ease score from 5 to 95 at 10-point intervals and took brief objective-type Comprehension Tests on them. "In general, differences between mean comprehension scores for adjacent RE levels were significant at the 5% level. From these findings it is inferred the Flesch RE scores do adequately estimate the comparative difficulty in comprehension of 'popular' reading material for a 17- to 18-year-old group."
