Ambassadors are sophomores, juniors, and seniors who have been chosen to represent the school at various events including Curriculum Night, Open House, New Student Registration, Baccalaureate, and Graduation. Also, they give tours to prospective students and visit schools promoting Blessed Trinity.  Students are nominated by their teachers in September each year and then must go through a rigorous application and interview process before possibly being selected to become an Ambassador. Once selected, Ambassadors are formally trained and expected to familiarize themselves with all aspects of the school.
