Each spring, Union conducts an early enrollment program for 3-year-old, pre-kindergarten and kindergarten students. 

• Children who are four years old on or before September 1 are eligible to be enrolled in the Pre-Kindergarten program at their home school for the coming year. The students must reside with a parent or legal guardian in the Union District. Pre-K is first come first serve on a space-available basis. Pre-K enrollment has to be completed, time stamped and approved by a district registrar in the Enrollment Center.
• Children who are five years old on or before September 1 are eligible for Kindergarten for the coming year. If you already have a student currently attending Pre-K in the Union District, the student will promote to Kindergarten at their home school based on your home address if they complete the school year.
