Questions

Questions about our standing

Is the affiliation permanent?

No CBSE affiliation is permanent. It runs for a fixed term and is renewed on inspection; ours was last renewed in 2022 and runs to 2027. The renewal date and the last inspection outcome are both on the Mandatory Public Disclosure page, not merely asserted here.

What is the difference between the UDISE+ code and the CBSE affiliation number?

The UDISE+ code is issued by the state education department and every school in India has one, whichever board it follows. The CBSE affiliation number and the CBSE school code exist only because we are affiliated to CBSE, and they are two different numbers even though they are often confused for one.
