> a teacher may not have time/resources to give extra content in kindergarten

A few weeks ago, I spoke with the principal at one of the most popular[0] public elementary schools in San Francisco. She told me:

- she's only had a student skip a grade once ever

- no matter how far ahead a child is, a kindergarten teacher will not teach any first grade content

The corollary holds true as well: schools are loathe to hold anyone back, even when the teacher & parents want to because of developmental delays or even a really late birthday. This is criminal.
