The task is to write a five-year plan which can be presented to potential donors who think about supporting the school.
It will give them a certain degree of security to know that there is a plan, to see what the school's goals are and how it is going to reach them.
Thanks to MariaZ for the excellent idea!

Check out the link below for the discussion, and some websites MariaZ found that have step-be-step guides etc.
This task is planned to be started after some brainstorming about how the school can become self-sufficient. See the link below for results.
