Mine is all in a package I give to parents at the interview - an about me page, a philosophy page, the contract, forms that would need to be signed and returned, page of references, usually a copy of my most recent newsletter, and a handout I found on learning that sort of goes along with the way I run my program.

We go over parts of the contract and I encourage them to read everything at their leisure and email or call if they don't understand something.
