Oklahoma’s kindergarten requirements differ from those of other states in that children must attend kindergarten, although the level of attendance can vary. For example, Oklahoma students five years old before September 1 typically must attend at least one half-day of kindergarten (two and a half hours). Public schools must, however, provide a full six-hour day for each child who has reached this age.
Families who want to enroll in kindergarten have options, including the online elementary school at Virtual Prep Academy of Oklahoma. We offer an accessible, supportive kindergarten alternative that is fully accredited. Read on to learn more about the Sooner State’s kindergarten requirements and how our online education programs can prepare your child for middle school, high school, and beyond.
Specific Kindergarten Requirements in Oklahoma
Oklahoma requires all children who turn five years old before or on September 1 to attend school unless excused. Children who are five may be excused from kindergarten until the following school year if their parent, guardian, or other custodial adult notifies their school of the decision by certified mail. There are some time constraints on this decision, so plan ahead and ensure you’re aware of all deadlines.
To enroll in kindergarten in the Sooner State, families must provide standard information: proof of age, residency, and immunizations (or exceptions).

While certified teachers provide live and guided lessons, you as their Learning Coach will remain closely involved and help facilitate their day-to-day.
