The USCCB issued a program for formation for US seminaries. Inter alia the conference has codified that Patristics (study of the theology of the Fathers of the Church) is to be included. Here are the relevant paragraphs:
201. Patristic studies constitute an essential part of theological studies. Theology should draw from the works of the Fathers of the Church that have lasting value within the living tradition of the Church. The core should include Patrology (an overview of the life and writings of the Fathers of the Church) and Patristics (an overview of the theological thought of the Fathers of the Church).
 See Congregation for Catholic Education, Instruction on the Study of the Fathers of the Church in the Formation of Priests (1989).
210. In historical studies, the core should include courses on the history universal and the history of the Catholic Church in the United States that way which reflects her multicultural origins and ecumenical context. Among the study of patristics and the lives of the saints are of special importance.
