Thank you for these comments. I'm just getting to them now as I was out of town for the weekend. He is 7, but will turn 8 in a few weeks.
By percentile higher for grade, I mean that he was 97 composite for age, but 98 composite for grade.
Even though it seems like his turning 8 in November might make him old for a second grader, where we are, in NC, it seems that his age is pretty average relative to his classmate.
I asked for some information on how the students did overall, at his school which is K-8, though I do not know if all grades took tests. This is what we were told (they refer to Iowa test, but what he had was CogAT, which I understand is put out by the Iowa company:
"The Iowa Test of Basic Skills (ITBS) results for your child were included ..... The ITBS is administered in the month of October in the Diocese of XXXXX to be used as a diagnostic/ prescriptive tool. These tests cannot be compared to the End of Grade tests given by our public school counterparts, as ITBS tests are used as a tool to help identify strengths and weaknesses. For example, it is expected that the students would not know all of the concepts in the Grade 3 test, because they have just begun Grade 3. Students who take the test in the spring would naturally have a different outcome than those who test in the fall. The parent copy of ITBS scores included your child�s National Percentile Ranking. Please keep in mind that this is not the same as percent. Instead, it is a comparative rank of your child to all others in his/ her age group nationwide. The 50th percentile is average. If your child scored in the 75th percentile, that indicates that he/she scored better than 75% of all students in his age group. School norms are also used to indicate the status or rank of the school compared to other schools in the nation. Score reports indicate that our school composite percentile rank average among all schools in the nation was 98.5%. Stanines are another way of understanding performance. Stanines essentially group percentile ranges by dividing them into 9 parts, with the largest number of individuals falling in the middle stanines. Our school�s score report was strong this year with a National Stanine of 7.5.
My son's stanines are 9, but since the school scored so high overall, I feel like he would be "average" for the school. Isn't that so?
However, I am going to look into the Duke and Hopkins evals mentioned.
Thanks again.
