    Dear Parents/Guardians,
    This year the Roxbury Public Schools will again be asking you to complete many of the back to school forms electronically in order to save the cost of postage, paper, and to continue our efforts to go green. The parent portal will be open for you to begin this process on Monday, August 15, 2016. School bus route information and class placement will be available through the Genesis parent portal beginning at 3:00 PM on Monday, August 22nd. Please note class placement information will not be available if you have not completed and/or acknowledged the necessary documents in the Genesis parent portal. 
    Short training videos are available on the website at to assist you in finding and signing off on the required documents. If you have questions, or need assistance in accessing the Genesis parent portal, please call the school Main Office at 973-584-8955 between the hours of 9am and 3pm.
    Jefferson School will hold an Open House on Wednesday, August 24th from 10am to 2pm. There will be a bus here to ride around the parking lot, PTA information and other fun activities.  Teachers may or may not be present but you can feel free to walk through the school and show your students where their new classrooms will be. 
    Thank you for your attention to these important matters and enjoy the rest of your summer.
    We can't wait to see everyone in a few weeks!

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!
