The revised Spache Readability Formula and the Fry Readability Formula were applied to 20 selected reading materials designed for adolescents reading at second grade level. Three samples from each text were examined. The results using the Spache formula corresponded to the publisher's stated readability levels, with no significant variability within books. But the results from the Fry formula were inconsistent with publisher's stated readability levels, and there was intrabook variability. (RL)
