HSML partners with credentialed and experienced teachers who work as independent contractors.  HSML teachers adhere to a high standard of professionalism both in the communication of mathematical principles and in their relationships with the students and parents.  Our teachers hold students accountable to excel in both their mathematical ability and in their growth and maturity as students, demonstrating increasing responsibility for their learning as they move into higher levels of coursework. We provide excellence but not conformity.  Variation among teachers and their teaching styles should be expected.
