The purpose of this article is to examine the importance of the most s
alient feature of a performance-assessment approach known as curriculu
m-based assessment: that testing material be drawn from the students'
instructional curricula. First, we review the literature on (a) the ma
tch between tests and curricula and (b) comparisons of measurement val
idity and instructional utility when sampling student performance in a
nd out of the instructional curriculum. Second, we discuss the potenti
al advantages and disadvantages of sampling performance in the curricu
lum. After concluding that sampling from the curriculum is not essenti
al, we discuss three critical features to ensure the instructional uti
lity of measurement.
