PreK

Pre-kindergarten (also called Pre-K or PK) is a classroom-based preschool program for children at or below the age of five in the United States, Canada and Turkey (when kindergarten starts). It may be delivered through a preschool or within a reception year in elementary school. Pre-kindergartens play an important role in early childhood education. They have existed in the US since 1922, normally run by private organizations. The U.S. Head Start program, the country's first federally funded pre-kindergarten program, was founded in 1967. This attempts to prepare children (especially disadvantaged children) to succeed in school.

The term "pre-kindergarten" is often used interchangeably with the concepts of "day care", and "child care"; however, these other early childhood settings focus their goal on substitutionary care for children while their legal parents/guardians are absent as opposed to pre-K's focus on skill building. They could involve academic training, or they could involve solely socializing activities.

Pre-kindergartens, though, differentiate themselves by equally focusing on building a child's (1) social development, (2) physical development, (3) emotional development, and (4) cognitive development. They commonly follow a set of organization-created teaching standards in shaping curriculum and instructional activities/goals. The term "preschool" more accurately approximates the name "pre-kindergarten", for both focus on harvesting the same four child development areas in subject-directed fashion. The term "preschool" often refers to such schools that are owned and operated as private or parochial schools. Pre-kindergartens refer to such school classrooms that function within a public school under the supervision of a public school administrator and funded completely by state or federally allocated funds, and private donations.
