Principal's Welcome

  • Dear High School Students and Families:

    We are delighted to begin another school year at CMHS and looking forward to helping all high school students realize their personal best and develop their strengths along the way.  Cohasset High School provides a rigorous course of study where independent ideas are encouraged and where passions are nurtured by a highly qualified and professional faculty.  The teachers, administrators, secretaries, and custodians are all committed to being role models for your students not only as academicians, but as people.  We take greast pride in maintaining a culture of civility and do our best every single day to ensure that students treat one another with respect.  That culture of positivity is strengthened by our strong relationsip with the school community and by the involvement of parents and caregivers in their students' education.  

    We thank you for your support and look forward to another year of student success at CHS!


    Mr. Scott, Assistant Principal

    Ms. Connolly, Principal
