Honor and respect for members of our school community, others, ourselves, and our environment are expected. Our goal is to help students recognize a mistake or poor choice and create space for them to respond in a positive way to the accepted standards of behavior we have collectively determined as important for a healthy school community. Consequences for behavior contrary to the values of THS and our accepted codes of behavior will vary dependent on the particular situation.
