You are not legally required to disclose your child's transgender identity to their school. The decision is entirely yours and should be based on what you feel is best for your child's well-being.
That said, sharing this information with the school may help create a more supportive and inclusive environment. When teachers and staff are informed, they can:
Use your child's correct name and pronouns.
Provide access to gender-affirming spaces (such as restrooms or locker rooms, where applicable).
Respond more effectively to bullying or discrimination.
Ultimately, whether to disclose is a personal decision. Consider your child's comfort, safety, and needs when deciding what information to share.
