... on the details of the tests themselves anc3 on their relationship to the educational experiences of the test takers. In the dynamic situation of educational reform today, the relevant subpopulations may even include those students to be tested in the next few years for whom there are no data currently available in a linking study clone today.

... However, the committee has reviewed the Anchor Test Study (Lores et al., 1972) , which clevelopec3 an equivalency scale for eight reading subtests, a number representing almost 90 percent of reading tests used at that time, at the cost of more than $ ~ million.

... , then the link permits comparisons of the results from both tests in similar terms. The validity of a link is supported by a strong statistical correlation of the scores from the two tests anc3 by the consistency of linkage across population groups, such as boys and girls, African Americans and whites, or residents of New York anc3 California.

... For example, CTB/McGraw Hill has linked the Califor' nia Test of Basic Skills with its newer Terra Nova test; Harcourt Brace Educational Measurement has linked the Stanford Achievement Test 8 with the Stanford Achievement Test 9; Riverside Publishing has linked the {owe Tests of Basic Skills M with earlier versions of the test. Sometimes the test specifications may have changed in response to shifts in educational emphases, anc3 the old anc3 new versions will not be as similar as two different versions of a test macle to the same specifications; however, old anc3 new versions can generally be successfully calibrated anc3 put on the same scale.

... First, NAEP content is cieterminec3 through a rigorous anc3 lengthy consensus process that culminates in "frameworks" cieemec3 relevant to NAEP's principal goal of monitoring aggregate student performance for the nation as a whole. NAEP content is not supposed to reflect particular state or local curricular goals, but rather a broac3 national consensus on what is or

... Thus, the portion of NAEP any one student takes is unlikely to be comparable in content to the full knowledge domain covered by an incliviclual test taker in a state or commercial test (see, e.g., U.S. Department of Education, 1997; National Research Council, 1996; Beaton and Gonzalez, 1995; U.S.
