School 10 (on Congress / the "old 37 School") is the South zone location for newly opened class enrolling 3 year olds in pre-K. You must submit application at the placement office and clearly say you want to be in the lottery for September 3 year old slot at School 10 (other zones are School 6 and School 41).
Our family loves pre-K and we are hoping 3 year old Maya will get a spot so she can be near her sister Sarah as she starts kindergarten at School 10!
No, it's half day. I'm not sure if there are morning and afternoon sessions, but you can follow the link above and contact Pat Dengler. Is your son 3? We should talk if you are planning for him.... maybe we can do some coordinating.
