Our district administers CogAT at one level higher than "typical"grade level as part of the assessment for the GT program. I understand that this is the publisher's recommendation due to ceilings at the higher end of the bell curve; however, I am having trouble finding information to clarify this. Does this mean that the Standard Age Scores on that end may be inflated? That percentiles are not accurate?
Also, the district uses grade rank percentiles. As I understand it, the raw score is used to find the Universal Scale Score. The USS is then
used to find the grade percentile. Age/grade is not taken into account as it is in SAS and age percentile rank. Wouldn't this mean that the GPR's show how students scored in relation to students in the NEXT grade (e.g. 2nd graders take LEVEL A and GPRs reflect performance relative to 3rd graders)? Any help os greatly appreciated!
