The Croton-Harmon School District embraces diversity in our workplace and in our schools. We are committed to building a team that represents a variety of backgrounds, perspectives, and skills. The more inclusive we are, the better we will be.  All available employment opportunities within our district can be found on our Online Application System.

"What makes Croton-Harmon Schools special? Without a doubt, it is the unique people who work in every corner of the district. In Croton-Harmon we remain committed to celebrating and acknowledging the outstanding individuals who are dedicating their lives in service of our amazing students. We hope you'll take a moment to review a growing collection of personal reflections from around the district. Enjoy!"
