Performance assessment is what teachers do every
day when they grade students' projects and assignments, but often this work
is not part of the high-stakes system that determines whether students are
ready to graduate--or whether schools as a whole are making progress.
while in the 1990s, that was starting to change, as states like
Connecticut, Nebraska, and Wyoming were developing large-scale performance
assessment systems. But the dawning of No Child Left Behind "pushed
aside" these efforts, because it was too costly for states to include
performance assessment in their statewide accountability systems under the
law, said Joan Herman, director of UCLA's National Center for Research on
Evaluation, Standards, and Student Testing.
