My son had lower scores in the spring of his 4th grade year than he did the previous fall. Since I had been homeschooling him, I knew that he had had tremendous academic growth during that time. I found out later that he had taken the 6+ level test in the fall and the 2-5 test in the spring (I don't have that reversed. The proctor in the fall understood that he needed a higher level test, and the proctor in the spring did not.). Perhaps the 2-5 test has a lower ceiling?
