Minnesota Rule 3525.0210 Subpart 43:

"Surrogate parent" means a person appointed by the providing district to intervene on behalf of a pupil, to help ensure that the rights of the pupil to a free appropriate education are protected. The surrogate parent shall not be a person who receives public funds to educate or care for the child. However, a foster parent may serve as a surrogate parent if appointed and if no conflict of interest exists.
