A lively and varied program of student activities is vital to the educational development of a well-rounded individual. Bishop Diego students are encouraged to explore their potential by becoming active members of the school community through participation in a variety of clubs and activities. Clubs and activities are driven by student interest and there are some years when a club or activity is added. Likewise, given student interests, there are some years when a club or activity hibernates to return in a subsequent year.

Student Government

Bishop Garcia Diego High School is proud to have an active student government to represent the entire student body; provide fun, responsible and diverse activities; and demonstrate youth leadership through school service. A student body president and class representatives for each class are elected each school year. These representatives receive credit for attending the Student Government class daily. 


Upon application, Bishop Diego students are invited to participate in the Bishop Ambassador program. Students carry out the mission of the school through word and deed by representing the school during public relations and outreach events at school and within our larger local community. Ambassador responsibilities include hosting visiting shadow students on campus and leading in Shadow Days and Open House, sharing their Bishop experiences. You may find Ambassadors at school and/or community events, wherever they are needed as representatives of the school. A sense of school pride and enthusiasm, leadership potential, work ethic, responsibility and commitment are a few of the qualities that describe a Bishop Ambassador.
