Trinity High School is a Catholic diocesan high school established in 1970 through the consolidation of Bishop Bradley, Immaculata, and St. Anthony High Schools. Its roots began in the nineteenth century with the founding of the first Catholic high schools in Manchester by the Christian Brothers, Sisters of Mercy and other religious orders. Its unique heritage also includes St. Joseph for Boys and St. Joseph for Girls, St. George, and St. Marie High Schools, all of which have left an indelible imprint on the community.
Trinity carries on that heritage of over one hundred years of commitment to intellectual and creative values with concern for the personal growth of the individual student. Most importantly, young men and women are challenged to go beyond academic excellence and to be committed to Christian values and standards of ethical and moral conduct.
Trinity promotes spiritual growth by helping students to grow in their knowledge of the faith and the teachings of the Church through a strong curriculum in religious studies. In addition to the academic program in religious education, programs of worship, community service, and campus ministry, help students to express their faith.
Its program of study helps the student to develop the ability to write clearly, to read and write critically, to analyze situations, and to solve programs. Young men and women are encouraged to develop the self -discipline necessary to achieve these goals. A variety of extra-curricular and athletic offerings provide for the student's social and physical development. Its motto, "Pride, Spirit and Tradition" expresses the bonds which keep the school community a vibrant one. (From the Introduction of the 1990 Alumni Directory)
