K-12 refers to kindergarten through 12th grade, covering ages 5–18.
Children are required by law to attend school between the ages of 7 and 17, though most children begin kindergarten at age 5.
Public schools are the most common and are tuition-free for residents, including international students or dependents of international students living in Missouri.
The education system is divided into three main levels:
Elementary School (Kindergarten – 5th grade)
Middle School (6th – 8th grade)
High School (9th – 12th grade)
Each school year typically begins in August or September and ends in May or June.
The school day usually runs from about 7:30 AM to 3:30 PM, depending on the school.
Public Schools: Funded by the government and open to all children who live in a specific school district.
Private Schools: Require tuition and may offer specialized education, such as religious instruction or specific educational philosophies (e.g., Montessori). Scholarships or financial aid may be available.
Homeschooling: Parents can choose to educate their children at home, though there are specific guidelines and reporting requirements.
