Three of the Kids’ CAT Results

For reasons I will explain in detail later, we gave the three older children the CAT full battery this year. Ani took the 8th grade CAT (she also took the 9th grade CAT-E Survey, but we don’t have the results yet), Cameron took the 5th grade CAT, and Fritz took the 2nd grade CAT.

Percentile means they did better than that many same grade level kids taking the same test (out of 100; for example, 90th percentile means they did better than 90 out of every 100 kids). Stanines give a quick look at their relative scores. 1, 2, 3 are below average, 4, 5, 6 are average, and 7, 8, 9 are above average compared to same grade level kids. The grade equivalent means they did the same as the average student of the given grade level taking the *same test* they took. The first number (before the decimal point) is grade and the second number (after the decimal point) is the month of that grade year. PHS means post high school.

We are absolutely thrilled by all of their results. We learned that while Calvert is generally phenomenal, their spelling is a bit behind. Fritz had exactly four words from his spelling tests through 2nd grade on his test. The other 24 words were all harder words. We also confirmed what we already knew about Cameron. He is very consistent. Back when he was tested for dyslexia two years ago, he was quite advanced in his vocabulary and comprehension and he still is and his spelling was way behind, and still is. We all got a good laugh over his spelling result, but it is so totally accurate. (Cameron did not use Calvert spelling. He used Sequential Spelling modified, but his result would be that low regardless of what spelling curriculum he used.)
