@Corcaigh we very much enjoyed Mercersburg visit as well. I had no idea about Dough Hale leaving. Chatted with many faculty members and current parent White Key volunteers. They were very enthusiastic. Swimming is offered all three seasons, a good size String Ensemble (about 16 kids, no orchestra as no Wind component). MAPS/SpringBoard program sounded amazing. They were yet to have STEM project though. I sat in Accelerated Precalculus class. They have Regular/Accelerated/Honors levels in math and some science. Majority of 9th graders take Algebra I or Geometry and Accelerated Precalculus is taken by 11th graders going into Calculus AB in 12th. It seems that there are few advanced math kids but Calculus 3 and Statistics are offered every other year and there are Robotics and Computer Science classes for kids who exhaust math early.
