My daughter is Student Teaching and is an Employee of a local private school. This is what I found on the S&D website:
Teacher and Education Support Staff Discount
All teachers and educational facility administrative personnel (includes colleges and universities) can take advantage of the TEACHER discounts. If you are a teacher with a certified teaching certificate, or you are employed in a school as an educational facility administrator you can take advantage of the TEACHER discounts.This would include teachers aides, substitute teachers, and administrative staff. These job types will require a Work ID or letter from supervisor on company letterhead stating employment or a recent Pay Stub.
Hope this helps -
