Principal's Message

  • Welcome

    Welcome to the Jefferson School Website!  Thank you for visiting.

    We are a PK-4 school located in beautiful Succasunna, NJ.  There are currently about 340 children attending, along with about 60 staff members.  At Jefferson School we are most proud of our commitment to Koala Kindness!  Students work with our motto "Carry on Koala Kindness" in everything they do. Our children demonstrate successful academic, social and emotional skills on a daily basis.

    We believe that learning is a Shared Responsibility.  At Jefferson, we are proud of our partnerships with the PTA, Community School, and many other programs that allow our children to rise to their potential.  Please enjoy exploring our website.  You can find a current "Week at a Glance" newsletter under the tab Our School.  

    Please feel free to reach out if you have any further questions regarding Jefferson School!
