Research documenting the validity of teacher judgment is, at present, shamefully hard to come by. About ten years ago, I read a brief monograph summarizing a few scattered studies that affirmed the validity of teacher judgment. The federally funded, master file on educational research called ERIC lists over 10,000 descriptors available for searching this comprehensive educational research database. As of 2001, “teacher judgment” did not even make list. The extent to which this obvious information asset is overlooked is one of the most appalling phenomena in education today.

How could we ever live with less standardized testing? How would we ever know whether the kids were learning anything?
