Preschool Registration

Registration Procedures 
Preschool registration will be held at the Princeton Public School’s Administration Building at 25 Valley Road. Please review the residency documentation requirements and required health forms on this website in preparation for your appointment. 

Open House Registration for the 2019-2020 school year has been scheduled for the following dates and times: 

Monday, February 11, 2019 from 8:00 AM to 3:30 PM
Wednesday, February 13, 2019 from 12:00 PM (noon) to 7:00 PM
Thursday, February 14, 2019 from 8:00 AM to 3:30 PM

Please contact the Residency Office to set up an appointment or with any questions at 609-806-4200, ext. 2061, or email

You can begin the pre-registration process by using our self-guided program, Registration Gateway.
Please note: this is only for pre-registering (your initial step); your registration will not be complete until you bring in the documents required to register to your child's school during the dates listed above. 


If more children register than spaces available, we will hold a lottery by the end of February for tuition spaces, and another lottery after Spring Break for non-tuition spaces. Parents will be notified soon after the lotteries are held whether or not their child's name was drawn in the lottery. Our goal is ensure that families have plenty of time to make a plan for preschool for their child before the start of the following school year. 

Preschool Disabilities Classes

Parents who suspect their preschool-age child may have special needs may obtain free help from the district’s Child Study Team. This team of district professionals works with families to locate and provide services for those children who are 3-5 years old who may have physical, cognitive, language, social, or emotional difficulties. Screening, professional guidance, and placement in a preschool educational program (if needed) are all available free of charge through the district’s Child Study Team. Additional information is available on NJ DOE Project Child Find and from the district's Student Services Office. 
Children eligible for a pre-school disabled class my attend at no cost. For further information contact the Princeton Public Schools’ Office of Student Services at 609-806-4200 x 2023 or 2027. 
Children under the age of 3 who demonstrate delays in development are eligible for free services through another Mercer County program called the Project Child Early Intervention Program. Parent training is also provided. 

Preschool General Education Classes

Any child who is four years old on or before October 1st and is a resident in Princeton is eligible to enroll. There are two general education preschool classrooms with 20 spaces per classroom. The general preschool classrooms are at Johnson Park and Riverside elementary schools. 

There is a tuition rate of $14,000 (adjusted annually), however, students who are eligible for free and reduced school meals are able to attend the general education preschool program at no cost.

Frequently Asked Questions

Is there a cost or tuition for the preschool program?
Students who are eligible for free and reduced school meals and students with disabilities are able to attend the preschool program at no cost. There is a tuition rate of $14,000 for all other students. Please note: the tuition rate is adjusted annually by the Board of Education and is subject to change. 
When does the program operate? 
The preschool program follows the elementary school calendar for holidays and early dismissal days. 
What is the daily schedule look like for preschool students?
The full-day program begins at 8:25 AM and ends at 3:00 PM. The preschool program follows the same calendar as our elementary schools. The daily preschool schedule includes greeting time, circle time, small and large group activities, interest- and activity-based centers, outside time, snack and lunch time, rest and quiet time, music time, and "plant-do-review" time where children select and plan their activities and reflect on them with an adult or peer.  Preschool classes also participate in "specials" that include physical education, music, and outside play time when the weather permits. 
Who teaches the integrated preschool class? 
Classes are taught by a certified teacher and a highly qualified teaching assistant who provides instructional support. 
What early childhood curriculum is used?
The early childhood curriculum that is used in the integrated preschool program is HighScope. A key feature of this research-based curriculum is the "active participatory learning" process where children make daily choices about their activities and teachers help them cultivate language, fine and gross motor skills, and social skills as they play.  
Are children required to be potty-trained?
Yes, preschool students must be potty-trained by the first day of school.
