Ah, finally, here’s a case with rumblings about test validity. Validity in testing requires that tests be used only for the purpose they were created. Here’s a lawsuit about the exam used by NYC to select students for its 8 exam schools have not been validated for the purpose they are being used. The complaint alleges that the exam is not validated to predict success in the selected schools–and thus should not be used as a criteria.

Go forth! I have argued for years that validity in testing should be central issue. Let’s see what happens here.

How about using student academic testing that measures how well they perform on state or common standards –as a way to measure teacher effectiveness! Again, where is the validity?
