You should be VERY VERY careful about believing what those Catholic school administrators tell you. In my experience, they lie casually and constantly. If your child attends religious instruction classes, they will study the Catechism, and they will learn sick, disgusting, awful things about LGBTQ people. The Catechism is a vicious document when it comes to queer folks. Yet I’ve had Catholic clergy tell me to my face that the Catechism isn’t homophobic. That’s how easily they lie. Never believe a word they say. They are very sick, evil people.
