Mich. Comp. Laws § 388.1769
In order for a public school academy to receive state aid under this act, the public school academy shall demonstrate to the satisfaction of the department that the public school academy has made a good faith effort to advertise, throughout the entire area of the intermediate district in which the public school academy is located, that the academy is enrolling students and the procedures for applying for enrollment. The department shall not make any payments to a public school academy until the public school academy supplies evidence satisfactory to the department demonstrating compliance with this section. If a public school academy is a successor to a nonpublic school and more than 75% of the pupils enrolled in the public school academy during its first school year of operation were previously enrolled in that nonpublic school, there is a rebuttable presumption that the public school academy did not make the good faith effort required under this section.
