Colonial School District
Colonial School District provides comprehensive education across New Castle County, Delaware, from early childhood through 12th grade. Families enrolling a child in Delaware public schools for the first time must complete feeder registration before submitting a School Choice application. Those pursuing elementary Spanish dual-language immersion must submit a Choice application even when assigned to the immersion campus as their neighborhood school. In the Spanish immersion classroom, kindergarteners divide instructional time equally between English and Spanish, covering core math, science, and literacy in Spanish. Choice families arrange their own student transportation or use designated bus stops within the school's attendance boundary, subject to available seating. Families planning ahead for the 2027–28 school year should review the district's feeder realignment plan, which outlines neighborhood attendance shifts scheduled for August 2027.
