Ronald P. Carver, professor of educational research and psychology at the University of Missouri in Kansas City, has charged that the College Board's "Degrees of Reading Power" (drp) test--which purports to match students' reading ability with appropriate instructional materials--is invalid and should be recalled.
The drp test, developed in 1969 and first adopted in 1982 by the Boston Public Schools, measures students' individual reading abilities in drp units, according to the College Board. After the tests have been scored, teachers may choose for their students books whose "readability" has been calculated on the same drp scale, the board says.
The board charges clients, including school districts and publishers, from $88 to $441 to analyze a book's readability; to date, it has analyzed 3,000 texts according to the drp model.
After conducting what he terms "extensive" research, Mr. Carver concluded that the test appears to have "large internal inconsistencies that render it invalid as a method for teachers and school personnel to use when forecasting which textbooks to select for students varying in reading ability."
Furthermore, the researcher argues, attempts to match students' drp-ability scores to the drp-difficulty scores of instructional materials are "likely to result in inappropriate selections of textbooks or other instructional materials."
Mr. Carver said that he has notified the College Board of his findings but that no changes have been made to the test.
Stephen H. Ivens, executive director of the drp program, responded to Mr. Carver's charges by noting that "if you interpret [the scores] the way he does, it does lead to illogical results." The board, he said, does not use the test in the way Mr. Carver claims. Furthermore, according to Mr. Ivens, Mr. Carver is the author and publisher of four competing reading tests.
Mr. Ivens also noted that an independent review panel studying Mr. Carver's charges had not agreed with his findings.
Britannica Learning Corporation, a division of Encyclopaedia Britannica Inc., has acquired American Learning Corporation, which provides private, individualized instruction in reading and preparation for the Scholastic Aptitude Test.
Robert P. Gwinn, chairman of the board of Britannica, said in a prepared statement that he intends to "rapidly expand" alc's scope by establishing learning centers throughout the United States by 1990.
"We see a tremendous need throughout the country for private learning centers, particularly those that can improve read-ing skills as dramatically as the alc program has demonstrated," said Stanley D. Frank, president of Britannica Learning Corporation.
Britannica will assume responsibility for "The Reading Game," an alc program that provides basic reading instruction in small-group sessions. The program has been selected by the National Institute of Education and National Right to Read as "effective in improving reading achievement," according to the firm.
