Welcome to TA’s website!
Whatever brings you here – whether you are a current or prospective student, a panther parent or grandparent, a TA alum, a community supporter, a curious educator, or just an interested Upper Valley neighbor – we hope you find stories, facts, and program information about Thetford Academy that are useful and compelling and that capture the unique and inspired nature of our school.
The Head of School page allows me to share my weekly family letters and other blog posts with the wider world. Topics range from program highlights and parent reminders to student shout-outs and class projects – and so much more. Most importantly, I try to spotlight all of the exciting activity happening on our campus and offer a window into daily life and learning at TA.
