The Beta Club recognizes outstanding achievement, promotes character and social responsibility, encourages service involvement to school and community, fosters leadership skills, grants scholarships, and provides settings for development of interpersonal relationship skills. Students are required to complete school-related volunteer service and community volunteer service.

Student Government Association (SGA)

SGA acts as the voice of the students to the administration. In addition, SGA plays a vital role in the life of DCS. These students make an impact school-wide through organizing student-led prayer and bible studies, assisting the Admissions & Development Offices by giving tours and speaking at various promotional functions, welcoming prospective and new student families to the school, and planning student events. SGA works closely with administration to provide a wide range of student led activities that impact DCS and the surrounding community.
