Should I make her attend?

My daughter (10) is going through puberty. She has acne, developing, new hair, started her period etc. I've helped her through most of it and some things, like her period (other then how long and how often) she doesn't want to talk about. Her 4th grade class is having a 1 hour class about puberty next week. Basically what to expect your body to go through. Its split boys have their own and girls have a separate so their not together. I have to sign a permission slip saying it's okay or not okay for her to attend. She doesn't really want to attend but I think it will be very helpful for her and maybe make her more comfortable with her body changes etc.
