I copy/pasted this from a pdf (I HATES PDFS). Anyway, reading laws makes me tired, but from what I can gather the Parental Rights in Education statute was expanded to 12th grade by the Florida dept of Education. So they didn't change the law itself, but made it apply to all grades.
6A-10.081 Principles of Professional Conduct for the
Education Profession in Florida.
(1) No change.
(2) Florida educators shall comply with the following
disciplinary principles. Violation of any of these principles shall
subject the individual to revocation or suspension of the
individual educator’s certificate, or the other penalties as
provided by law.
(a) Obligation to the student requires that the individual:
1. through 5. No change.
6. Shall not intentionally provide classroom instruction to
students in prekindergarten through grade 3 on sexual
orientation or gender identity.
7. Shall not intentionally provide classroom instruction to
students in grades 4 through 12 on sexual orientation or gender
identity unless such instruction is either expressly required by
state academic standards as adopted in Rule 6A-1.09401,
F.A.C., or is part of a reproductive health course or health
lesson for which a student’s parent has the option to have his or
her student not attend.
8. 7. Shall not intentionally violate or deny a student’s legal
rights.
9. 8. Shall not discourage or prohibit parental notification
of and involvement in critical decisions affecting a student’s
mental, emotional, or physical health or well-being unless the
individual reasonably believes that disclosure would result in
abuse, abandonment, or neglect as defined in Section 39.01,
F.S.
10. 9. Shall not harass or discriminate against any student
on the basis of race, color, religion, sex, age, national or ethnic
origin, political beliefs, marital status, handicapping condition,
sexual orientation, or social and family background and shall
make reasonable effort to assure that each student is protected
from harassment or discrimination. Discrimination on the basis
of race, color, national origin, or sex includes subjecting any
student to training or instruction that espouses, promotes,
advances, inculcates, or compels such student to believe any of
the concepts listed in s. Section 1000.05(4)(a), F.S.
11. 10. Shall not exploit a relationship with a student for
personal gain or advantage.
12. 11. Shall keep in confidence personally identifiable
information obtained in the course of professional service,
unless disclosure serves professional purposes or is required by
law.
