About the NYC public school system: my cousin went to an overcrowded NYC school and one way they solved the problem was to have 2 shifts of the school day – I think it was like 7-12 and 12-5? Something like that.
Also, who here would allow their children to go to a coed school? Raise your hand, but I doubt its more than 1-2 people.
In Bergen County, NJ a Hebrew Language charter school was just approved. Its called Shalom Academy. Its a hebrew immersion and a Talmud Torah will take place (on or off campus, I’m not 100% sure), and cost very little. Rumor has it the TT is well backed and will cost just a few hundred dollars per child per year. Likely, there will be a before school tefilla club.
In a place like Bergen County, this has a lot of potential for success. However, it is still a public school and religion will not be a part of it. The school cafeteria will be kosher (or have a kosher option, details are still sketchy), but non kosher food may be brought it. Schools will not be closed on all Yom Tovim, but will obviously not penalize a large portion of the students for taking off.
I will post a link to their website if the mods will allow it.
