Early Childhood Screening is a FREE, one-time, growth and developmental check required by the State of Minnesota for all preschool aged children (ages 3-6) entering school in Minnesota, including JumpStart Preschool or Kindergarten. It is best done when your child is around 3 years of age. All students entering a Minnesota public school for Preschool or Kindergarten MUST have it completed within 90 days of the start of attendance. Screening appointments are held at Probstfield Center for Education, 2410 14th St S, Moorhead. Screenings are offered about twelve times throughout the year.
