# Pre-Kindergarten — Definition & Explanation > From the SchoolBrowse Education Glossary. > HTML version: https://schoolbrowse.com/glossary/pre-kindergarten **In short:** An early childhood education program for children typically aged 3-5, preparing them for kindergarten through play-based learning. **Pre-Kindergarten** (Pre-K) is an early childhood education program for children typically between ages 3 and 5, designed to prepare them for the academic and social demands of kindergarten. Programs focus on developing foundational skills through age-appropriate, often play-based activities. ## What Children Learn Pre-K curricula typically cover early literacy (letter recognition, phonological awareness), numeracy (counting, shapes, patterns), social-emotional skills (sharing, self-regulation), and motor development. The emphasis is on learning through exploration, play, and hands-on activities. ## Types of Pre-K Programs Pre-K programs are offered by public schools, private preschools, Head Start, and community organizations. Some states offer universal Pre-K, providing free programs for all four-year-olds. Program quality, hours, and costs vary widely. ## Frequently asked questions **Q: Is Pre-K the same as preschool?** Pre-K and preschool are similar but Pre-K typically refers to the year immediately before kindergarten (age 4-5) and may have more structured academic preparation. **Q: Is Pre-K mandatory?** Pre-K is not mandatory in most states, though some areas have universal Pre-K programs. School attendance typically becomes required at kindergarten or age 5-6. **Q: What should a child know before Pre-K?** No specific skills are required. Children benefit from basic self-care abilities (using the bathroom, eating independently) and some exposure to social situations with other children. --- Source: SchoolBrowse Education Glossary (https://schoolbrowse.com/glossary).
