In the summer of 2011, Sr. Katarina Schuth, OSF, completed the analysis of a survey of Pope St. John XXIII alumni, taken earlier that year. The ages of the respondents ranged from 45 to 84, with a median age of 62. The survey indicated that 90% of the respondents were still active in ministry, 7% semi-retired, 1.5% retired and 1.5% had left the priesthood. Sixty percent of respondents were pastors of parishes, with 20% serving as chaplains. Ninety-six percent described themselves as 'happy' or as 'very happy' in their ministry.
Those surveyed were asked to rate on a scale of 1 (not well prepared) to 5 (well prepared), how well the seminary prepared them for priestly ministry. In the area of pastoral formation, the seminary received an average rating of 4.51 out of 5.0. In the area of intellectual formation, seminary received an average rating of 4.47, in spiritual formation, 4.45, and in human formation 4.36. Overall, the alumni felt themselves well prepared for priestly ministry by Pope St. John XXIII.
