A preschool operated by the Sonoma United Methodist Church, the Sunshine School is located in a single-level structure behind the church facilities on Patton street, just south of the Plaza off of 1st Street West. The school boasts an extensive playground, with play houses, a sandbox, a farmers market play-area, a racetrack play-area, a shaded outdoor cafeteria and open field space. Students are required to attend a minimum of two-days per week, and extended-care options are offered for working parents. The curriculum is focused on giving children "hands-on" learning experience to develop social, cognitive and physical skills; therefore, outdoor education is emphasized. The students are divided into Minnows, who are 2-3 years old, Starfish and Angels, who are 3-4 years old, and Dolphins and Whales who are 4-5 years old. Potty-training is not required for enrollment.
