A few of the changes to this edition include: the requirement that employers assess whether referenced exams meet their requirements; restrictions on the use of eye drops to improve vision; the requirement that proctors administering written examinations are trained; some definitions were clarified; and CR, DR, and CT image interpreter requirements were added.
