Each secondary student at ISH takes part in an Advisory class that meets for one period each week. Advisories help to create a more personalized learning environment where all students are well known by at least one adult. Advisory's purpose is to develop a sense of community through a program that:

 a) endorses the enhancement of emotional wellbeing,

b) recognizes and values the development of resilient young people who feel a sense of belonging and connectedness, and

c) promotes a sense of meaning and purpose in life.

Advisory periods are not meant for students to complete their schoolwork. Sometimes advisory periods are used for activities such as assemblies or guest speakers.
