We want to extend a warm welcome to the Class of 2027 and to all students and staff who are new to our building this year. In addition, we want to welcome all returning students and staff back to Commack High School. We are looking forward to seeing you and having your energy and enthusiasm fill the building.

One of the keys to making this year a successful one is to be engaged in all that CHS has to offer:

The entire building - the Administrative Team, the teachers, the counselors, the mental health team, the school nurses, and the support staff are here to help you become the best version of yourself and to help support and guide you in this endeavor. We are Proud to be CHS! 

Wishing everyone an absolutely amazing year and we look forward to celebrating and highlighting all the amazing discoveries you are going to make, all the accomplishments you are going to achieve and all the successes we know that you are going to have!
