Really supportive community, check it out!
I think that true pre-admissions trying to get a fit or get to know the professor sample lesson usually happens between the spring of Junior year and fall/winter of Senior year. There are also some sample lessons and conversations when students are trying to choose a school from the list of schools that accept them by that point. But there are some exceptions, for example if students have a chance to schedule these lessons during summer festivals - with program instructors or visiting musicians.
What is the goal of having her have the sample lesson so early? Your daughter should also seek advice from her private teacher. Private teachers are usually guiding their students through the application process, and they know the kids they teach and their abilities really well!
Good luck!
