These screenings help identify any potential developmental, health, or learning concerns early on. What Does the Screening Include? Developmental Screening – Checks cognitive, language, motor, and social skills. Vision & Hearing Tests – Identifies any early signs of issues. Height & Weight Measurements – Assesses growth patterns. Immunization Review – Ensures vaccines are up to date. Health & Family History – Helps identify any concerns that may affect learning. Who Needs a Screening? Children aged 3-5 (ideally around age 3). Required before kindergarten enrollment in Minnesota public schools.
