School Notes

  • IMS is more than a school. It's a diverse and inclusive environment grounded in meaningful relationships, where children are encouraged to be curious, to take risks, and to embrace the adventure of learning while also celebrating the joy of childhood. Together, our teachers and students navigate an increasingly complex world with intellect, creativity, equity, and optimism. We don't shy away from difficult conversations; we approach them with honesty, compassion, and respect. The Mountain provides a unique learning environment for both day and boarding students, from Pre-K through Grade 9. At IMS, we believe that growth rarely follows a straight line. It takes courage to stray from the expected path, and that courage is something we witness every day in our students, guided and supported by an exceptional team of educators and staff. Thank you for your interest in Indian Mountain School. We are eager to welcome you.
