What permissions need to be granted


I lead a course at a 16 18 college in the UK. I would like to register for Sketchup for Schools but need some help. I tried to log in but got the message about needing an admin to grant permissions. Can you help me clear up what permissions need to be granted. I approached our IT technicians and they werent sure what the admin needs to do or what level of admin needs to action this.
