Children who turn 4 years old on or before Sept. 1 of the program year are eligible to attend VPK. In addition, as of July 2016, parents with children born between Feb. 2 through Sept. 1 may postpone enrolling their child in VPK the year they turn 4 and wait until the following year when their child is 5, as long as the child has not yet been admitted to kindergarten.
