You will need to seek assistance from your School's IT Administrator.

Your School's network may (is perhaps very likely to) have protective measures deployed to intercept and monitor your internet traffic when connected to their network. Assuming that full packet-inspection is being used to monitor your internet traffic, this monitoring can cause the certificate trust-chain to be disrupted - potentially causing your iPad to display the error that you illustrate.
