A Note on the Word Identification Subtest of the Woodcock Reading Mastery Tests-Revised: Different Classification Consequences of Forms G and H

Forty-eight students, randomly selected from among fifth-grade children who were participating in a re-test estimation study, were administered Forms G and H of the Woodcock Reading Mastery Tests' Word Identification subtest in a counterbalanced format. Analyses of the data indicate that the two forms of the subtest are not parallel. While a correlation between the scores on the two forms of the subtest was high (r = .86), classification reliability was poor; statistically significant levels were reached for both grade classification and quartile classification inconsistencies between the forms. Implications of these findings for the subtest's use in Woodcock profiles are discussed.
