My kid scored in the 108th percentile and I was upset he wasn’t being challenged too |
Davidson is different. It’s for the 0.001 percent. CTY is a better bet. If your kid were Davidson gifted, you would know it. Many are ready for college in 7th grade. (No bragging here, mine is not that kind of kid either but I know 3 of them.) |
From Chatgpt:
Bottom line / practical guidance If you care about how many students in your grade actually show up as 99th percentile on an ERB report, expect variability — small grades, ties, subject differences, and whether your school compares to independent vs national norms can make that observed fraction higher or lower. For stanine 9 (top band, 96–99) expect roughly ~4% of a large norm group to fall there. In a class with 50 kids total, that would be 2 kids that got 96-99%. |
I’ve worked in a variety of independent schools, and I’ve seen the span of ERB scores. There are a few things to know. We see students who are great at taking tests but not exceptional at in-class work. Some of these students have really great recall of information but weaker skills in the higher-order thinking that is required for a research project or multi-step mathematical reasoning—things the ERB does not test. It’s also unusual for a child to be 98th or 99th percentile in both math and language. That said, in an elementary grade cohort of 30-60 students at a good but not extremely selective school, I would see one to four students score that highly per year. I would also have one or two students who would score in the single-digit percentiles. Usually, these were students with diagnosed learning disabilities who were perfectly able to access the curriculum but who found standardized testing to be challenging. When class sizes were 10-20 students, the range of abilities was very large, and I was only provided with one curriculum, it was very difficult to get every student a “just right” level of instruction.
Look for schools that ability group for math and reading. Your child might still stand out as strong in the more challenging classes, but there will certainly be material that is appropriately difficult and engaging. |
Joke missed. |
What's the difference between ERB and ISEE? I know the latter is only an admissions test, but they seem to be administered by the same company. Are the percentiles equivalent? (I.e. is one predictive of the other?) |
