In schools throughout the country, it is testing season--time for students to take the Big Standardized Test (the PARCC, SBA, or your state's alternative). This ritual really blossomed way back in the days of No Child Left Behind, but after all these years, teachers are mostly unexcited about it. There are many problems with the testing regimen, but a big issue for classroom teachers is that the tests do not help the teacher do her job.
Folks outside of schools often imagine that one of the benefits of the test is to check to see how students are doing and adjust instruction accordingly. Unfortunately, the tests provide no such benefit.
