Roaming profiles help

Guys, i need help. We have a roaming profile setup in a college environment on AD, where staff have roaming profiles and students do not.
I would like someone to help with a script to deploy using Group policy to remove all the roaming profile cache of students from the PC , all the pc’s are on AD. The script or soulution should be selective of just removing student local profiels and not staff’s. The students username starts with 2 and 3, PLEASE HELP ME.

Thank you very much in advance.
