“Teacher tests” often have different objectives than solely measuring one student’s ability compared to another. Likewise, the investments made in the creation of standardized tests are not likely to be matched by classroom teachers due to logistical constraints even if they have the necessary knowledge to create an equally valid assessment.

The objective should be the creation of a system that allows teachers to retain the flexibility to modify curriculum in a manner appropriate to their specific student population while also maintaining the trust and reliability benefits found in standardized tests.
