[quote=Anonymous]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%.[/quote]
