The easyCBM program has random placement of test responses and answers

Letter placement of the test answers (such as a, b, and c) have answer options that automatically/randomly switch positions — this is an important tenant of Universal Design for Assessment and high quality selected-response item writing. Thus, when students are going over their answers and practicing, they should focus on their actual response (and not their choice of a, b, or c in the online test administration). The rotation of the answers is to help cut down on cheating should a student try and look at another student's screen or answer sheet.
