A focus of the Common Core State Standards/English Language Arts (CCSS/ELA) is that students become increasingly more capable with complex text over their school careers. This focus has redirected attention to the measurement of text complexity. Although CCSS/ELA suggests multiple criteria for this task, the standards offer a single measure of…

Takes issue with E. Fry's widely accepted claim that the average readability of a book is ascertainable on the basis of only three samples; reports that numerous samples were needed to estimate readability means of 36 basal workbooks. (MKM)

Concludes that the Spache and Harris-Jacobson readability formulas are quite similar in variables used, in the way they were developed, and in statistical characteristics; notes differences in the Fry graph and raises questions about its suitability for measuring the readability of primary grade reading materials. (ET)

Responds to doubts raised in the preceding article about the author's readability graph. Defends the orthodoxy of the procedures used to develop the graph and presents data showing that it correlates quite well with the other formulas on first- and second-grade materials and is just a little high on third- grade materials. (ET)

Attempts to determine whether the Raygor graph produces readability estimates compatible with estimates derived from the Fry graph, whether the Raygor graph is less time-consuming, and whether it lends itself to greater computational accuracy. (DD)

Reports that the McCall-Crabbs Standard Test Lessons in Reading were never sufficiently standardized to justify their widespread use as the basis for readability formulae. (DD)

This paper describes and reports on the performance of six related artificial neural networks that have been developed for the purpose of readability analysis. Two networks employ counts of linguistic variables that simulate a traditional regression-based approach to readability. The remaining networks determine readability from "visual…

"Lasbarhetsindex" ("Lix") is a readability formula developed in Sweden that holds promise for assessing text difficulty in other languages, including English. So far three separate studies have been conducted to test Lix with French and English texts, with German and English texts, and with Greek and English texts. In all three…

In a response to the Mikulecky and Diehl examination of work-related literacy, this paper points out the need for data based on ethnographic approaches to research and more realistic assessments of text difficulty. Also suggested are questions to which future research might respond: How much of functional literacy is really functional competency?…

This report was prepared to assist the United States Army in evaluating the usefulness of readability formulas in identifying material that will be comprehended by readers at a given reading skill level. Existing readability methods and research findings were reviewed against three major criterion questions and the findings are discussed. The…
