The Common Core State Standards and accompanying K-12 assessments have recently sparked a fierce national backlash against testing. Sound educational testing and assessment are integral to good teaching and learning in classrooms and necessary for evaluating school performance and assuring quality in education. Rather than throw the baby out with the bathwater, I propose a more considered, "mend, not end" approach to testing, assessment, and accountability in America's schools, with validity at the forefront of the conversation.

Mending begins with understanding that most commercial standardized tests are designed to serve particular purposes well, for particular populations, and can support only particular decisions at best. To uphold validity principles in practice, it is worthwhile to ask: Are we using the test for the originally intended purpose, or for another purpose that taxes the tool beyond its technical limits? Multi-purposing a test indiscriminately is not a good idea from a validity standpoint, despite its efficiency.
