Three hundred sixty-one seminarians from the 48 diocesan seminaries in the United States and the North American College in Rome, Italy responded to a survey regarding their sentiments about the value of Catholic schools, their effectiveness, and the importance of financially supporting them. The results suggest that while diocesan seminarians are generally supportive of Catholic schools, they are more positive about the value of Catholic schools and the importance of providing financial support than they are about the effectiveness of Catholic schools, especially their religious effectiveness. The seminarians’ sentiments toward value and financial support are comparable to those of previous studies of priests. The seminarians’ own backgrounds in Catholic schools, selection of the most important purpose of Catholic schools, age, Hispanic ethnicity, and whether the seminary provided academic instruction about Catholic schools are factors that influenced their sentiments, particularly of effectiveness. The study did not include seminarians from religious congregations.
