  • College Essay Hacking the College Essay

    Are you a rising senior about to begin the college application process? Are you the parent of such a student? Do you have questions about crafting a college essay that will optimize college admissions’ consideration of you (or your child)? Do you want to avoid spending exorbitant fees on a tutor whose experience in this domain is questionable? Then come to the Hacking the College Essay lecture at the CMHS Learning Commons on Monday, June 18th from 6:30 to 8:00 p.m.

    Mr. McCabe and Mrs. McInnis, who have read and advised students on thousands of college essays, will demystify the college essay process. This is a free event.

    If you are able to attend, please email Mr. McCabe at Please specify the names and the number of people who will be in attendance.

  • Image result for poison ivy clipartDear Cohasset Families,

    We have been notified that poison ivy has been detected in areas around the Joseph Osgood and Deer Hill Schools.  DPW will be treating those areas on Sunday, June 3, 2018.  That means some areas will be off limits until Tuesday morning. This will not affect the recess play areas Monday or Tuesday. However, I ask that Sunday be off limits to all areas around the outside area of both schools.

    Thank you,

    Louise L. Demas, Superintendent

Principal's Welcome

  • Dear High School Students and Families:

    Our first semester is winding down and students will be studying for Sem I final exams before you know it!  Seniors are learning about acceptances to schools and are making important decisions about their future plans.  Amidst all of that, the student body of Cohasset is impressive for the number of students who are truly dedicated to doing their best.  We try to help them strike a healthy balance between academics and co-curricular activities, and appreciate that we partner with families in doing so.  I hope students and families are able to enjoy the break and have a little down time.  

     Every day at CMHS, I endeavor to foster a culture of mutual respect, and believe it is my moral and ethical responsibility to ensure that all Cohasset students are able to learn in a safe environment. I appreciate the tremendous trust you and your family have placed in the schools, and want you to know that it is a responsibility I bear with great pride. I recognize that the school’s continued success is the result of students’ accomplishments and the community’s dedication to excellence

    Best wishes for a happy and healthy New Year!

    Carolyn M. Connolly
