I am a year 11 student and have been attending this private school since year 7. In year 7, they made my parents sign a contract in which they outlined that students are not allowed to grow facial hair. Now my beliefs have changed and I no longer want to shave. I don't want to change schools as this school is the only good one in my area. And even if I do, I wouldn't get the right subjects and it would be detrimental to my education. So, taking into account my situation, what are my rights/options?
