According to About.com Working Moms, a preschool is defined as any school experience provided to children who are too young to attend kindergarten. Children who attend preschool typically start between two and three years of age.
Preschools do not delve deeply into academia. Most preschools focus on social development, peer interaction and introductions to basic concepts, such as letters and numbers, in order to prepare children for kindergarten. Preschool also often functions as childcare for parents who work outside the home. Parents can choose between a wide variety of preschools that best fit their needs and parenting styles. Three common styles include Montessori, Waldorf, and child-centered.
