The Council of the Great City Schools, launched a survey to determine how much testing is done in US public schools and how the tests are used. The survey result which was released on Saturday October 24, 2015 found that about 112 mandated tests are given to students in US big cities between prekindergarten and 12th grade.  Advanced Placement and ACT tests are not included in the survey’s count.

The survey also found that spending time on tests did not improve the academic performance of students using the National Assessment of Educational Progress, as a measuring tool.
