I have posted online the resources I have created for Drama Ambassadors.
It includes a Handbook that all students who are successful in getting the position recieve. In the handbook at top tips for planning a rehearsal schedule, planning a workshop and behaviour management in the drama room.
There is the job description and application process that the students need to go through to become a drama ambassador.
There are some examples of completed workshop plans and rehearsal schedules along with the blank templates for students to complete.
All of these can be downloaded and adapted or used by you from: http://www.tes.co.uk/teaching-resource/Drama-Ambassadors-6343326/
