If you have an interest in the age at which children are admitted to kindergarten, you might want to read about the current wrangle in Westborough over the news that 13 Westborough kindergartners are attending school in Worcester. In order to attend kindergarten in Westborough, a child has to have turned six by September 1; in Worcester, by December 31.
We have quite a number of families that avail themselves of Worcester's later date (and you might remember, when we asked a bit ago if it was hurting our test scores, the answer--surprisingly--was no). These are school choice students, so their sending districts send Worcester $5000 in school choice funds per pupil.
I should also point out that state law says that you must be allowed to enter grade 1 once you've completed kindergarten.
