Education Relationships Rules

We are beginning a review of our Educational Constituent in Tessitura?

Similar to my last question.

What are the Relationships you setup for your constituents that are involved in educational events?

Do you use any types of special "relationships" in an educational context?

For example is a Teacher an Employee of a school or even a school district.  Or do you have a special relationship type for Teacher?

Do you maintain a special relationship type for Students when you relate them to a school?

If you capture Student Names in some cased do you relate them to a specific teacher at the school?  Or the School itself.

Are Teachers Primary Affiliates of Schools or are just the Principles Primary Affiliates?

Do you do Mother Father Relationships to Children or do you just relate the children to a particular household or both?

What are the most important relationships to capture?  And why?
