At Holton a couple years ago, they pretty much refused to speak with 9th/10th graders which at the time was frustrating. However, the program was very strong for 11th/12th and matriculation was strong so which is what really matters.
Holton was also more transparent/honest than our other child's school in terms of ED chances, etc. Their counselors shared if lots of legacies were applying, where kids fit in terms of stats within the general group applying, etc. which was very helpful to manage expectations and apply appropriately.
In general, from a parent perspective, if your child gets into the college of their/your choice, you will leave thinking counseling and overall the school was great. If not, you'll be meh to waste of $$$$$$ in your opinion of them.
