This is possible if they chose a test with a low enough ceiling - such as an 'are you ready for this grade?' pretest of the last grade's skills, or even a test of current grade skills. (You can't really get better than 95-100%, right?) Your DS's abilities may not appear different unless they do an out-of-level test, which they would obviously rather not do.
