Because standardized tests are presented in a multiple choice format‚ a teacher cannot‚ for example‚ see where a child went wrong when he or she failed to solve a math problem correctly‚ because no work is shown. In addition‚ critics feel that the questions on standardized tests are too simplistic for children to fully demonstrate reading comprehension
