So far, I am leery of both sets of official tests for the Common Core, at least in English language arts (ELA). They could endanger the promise of the Common Core. In recent years, the promise of NCLB was vitiated when test prep for reading-comprehension tests usurped the teaching of science, literature, history, civics, and the arts—the very subjects needed for good reading comprehension.
In an earlier Huffington Post blog, I wrote that if students learned science, literature, history, civics, and the arts, they would do very well on the new Common Core reading tests—whatever those tests turned out to be. To my distress, many teachers commented that no, they were still going to do test prep, as any sensible teacher should, because their job and income depended on their students’ scores on the reading tests.
The first thing I’d want to do if I were younger would be to launch an effective court challenge to value-added teacher evaluations on the basis of test scores in reading comprehension. In the domain of reading comprehension, the value-added approach to teacher evaluation is unsound both technically and in its curriculum-narrowing effects. The connection between job ratings and tests in ELA has been a disaster for education.
The scholarly proponents of the value-added approach have sent me a set of technical studies. My analysis of them showed what anyone immersed in reading research would have predicted: The value-added data were modestly stable for math but fuzzy and unreliable for reading. It...
