Public or nonpublic school students in grades K-12 may refuse to dissect animals, observe dissection or participate in any project, including tests, involving the harmful or destructive use of animals. In this case the term “animal” includes severed parts of any animal’s cadaver. Schools shall notify incoming pupils and their parents or guardians of this right not less than three weeks prior to the scheduled course(s) involving the use of animals. Parents may refuse to allow their children to participate in such projects. Any pupil who chooses not to dissect shall be offered an alternative assignment and shall not be discriminated against based on his or her decision to exercise this right. It is strictly prohibited to lower the grade of a student who has chosen an alternative education project. School Code PA 30, No. 14 Section 2, 1522 (1992).
