Powell, William R. – Int Reading Assn Conf Proc Pt 4, 1968
Offers evidence to show that the commonly used Betts-Killgallon word recognition criteria of 95 percent for designating instructional reading level is too high. A recent study of the informal reading profiles of 178 average-achieving first-through-sixth graders is included. Bibliography. (CM)

Presented is a critical inquiry about the product of the informal reading inventory (IRI) and about some of the elements used in the process of determining that product. Recent developments on this topic are briefly reviewed. Questions are raised concerning what is a suitable criterion level for word recognition. The original criterion of 95…

Drawing on results from informal reading inventories and studies of oral reading behavior, a theory is presented to describe the process of learning to read. Reading is seen to be broader than a skill and more like a repertoire with many abilities, aptitudes, and special accomplishments performing in concert. This repertoire is acquired in four…

The widely accepted 95 percent word recognition criterion used for designating the instructional reading level is re-evaluated. A survey of the original study of Betts and Killgallon indicated (1) that the 95 percent word recognition criterion was based on a 41-case sample at the fourth-grade level, (2) that repetition errors occurred most…

Powell, William R. – 1976
Effective use of the informal reading inventory (IRI) depends upon the criteria used in determining the functional reading levels and more specifically the word recognition criteria employed in describing acceptable limits of oral reading behavior. The author of this paper looks at the diverse sets of criteria commonly used, the problems…

Powell, William R. – 1978
To improve the accuracy of the informal reading inventory (IRI), a differential set of criteria is necessary for both word recognition and comprehension scores for different levels and reading conditions. In initial evaluation, word recognition scores should reflect only errors of insertions, omissions, mispronunciations, substitiutions, unkown…
