Scheduled application control and web filtering
Application control and web filtering to be applied when students and staff are only at the school. Maybe ping 2 or 3 internal server and then apply the policies?
This will give users the ability to use what ever apps or any websites they want
when at home but at school they are restricted.

This is location based policy which I believe can be done if you have a Sophos firewall onsite...
Similar requirement. Basically if the Central Client is in the internal network, Web Control restriction should be disabled as the proxy/firewall provides the inhouse web restrictions. If the client is outside the network the Web Control policy must be active.
