Ujm: I think this discussion is about OOT in the US.
I think another big question is about mosdos chasidishe parents would feel comfortable sending to.
For example in staten Island I think people send into BP.
In Baltimore there is a very small chasidishe mosed.
Bloomingberg is satmar
Union city is zanz.
.In Chicago there’s veitzner cheder which is in Yiddish and people feel comfortable sending to, and girls go to the regular beis Yaakov.
