Pf applicaple on school affiliated to R.B.S.E Board - its not government aided

I am working in a school(Affiliated to R.B.S.E Board) on LDC post. I found that from the beginning that the school doesn't provide EPF facility although school comprises of 80 members. Please guide. The school was previously government aided but from around 2002 its not government aided.

The schools are covered under the EPF Act 1952 and your school is liable to cover it with retrospective effect. As soon as this fact comes to the knowledge of PF Inspector, they will initiate action to ensure the coverage.

PF of old employees is deducted at Treasury Account. Still EPF is applied?

It is stated that school is not Government aided, that would mean employees are paid by the school management, then how come employees PF is deposited in treasury. At the same time, since EPF Act extends to schools, it is applicable at least to the staff not covered under Govt Scheme (GPF)
