Cistercian Preparatory School is a Roman Catholic school for boys located in Irving, Texas, in the Roman Catholic Diocese of Dallas. Serving grades five through twelve (though previously having a 4th grade pre-form), the school has a population of about 350 boys. Each grade is assigned a priest or a dedicated teacher as a "Form Master," who follows the class over the years and is responsible for building a feeling of community. The school's roots lie with a group of Cistercians who came to Texas in 1956 to help found the University of Dallas, located adjacent to what would become the Cistercian campus. Later that year, an uprising in communist Hungary allowed a group from Zirc Abbey in western Hungary to escape, and they joined their colleagues in Texas. The monks of Zirc had a long tradition of teaching in the abbey's college preparatory schools, so in 1962 they started Cistercian Preparatory School to continue their work in secondary education.
