Girls’ schools generally start at 9:15 and boys’ at 9:00.
Ending times vary by school (and differ by age group within each school).
Busing is generally both ways (assuming you qualify for it or have paid).
(I find the question somewhat strange. Lakewood has more than 20 chadarim
and a similar number of Jewish girls’ schools. These are all private schools and
are not run collectively. The uniform start times are due to bus companies.)
