The TDOE clearly states that students may read a book or do an alternate activity not related to the subject being tested. Here, we'll copy that part for you:
This method has worked like a charm for parents so far. In fact, we are reading social media posts from parents in Hamilton County who report that one school has over 140 students opting-out! Students at that school whose parents refused the testing will be moved to another room to do another activity instead of test.
Hamilton County has some strong principals who are opposed to the TNReady testing use. In fact, the Hamilton County Principals's Association passed a Resolution stating that Part I of TNReady should be eliminated this school year and also that the scores from this year's testing should not be used for student grades, teacher evaluations, or accountability purposes. Go, Hamilton County Principals! We hope other districts read this and take action, too!
