Each (Arch)Diocese has its own method of financing seminary education. Most require that seminarians complete a Free Application for Federal Student Aid (FAFSA) each year, as well as applying for all scholarships and grants available. Please contact your Vocation Director to understand what the policies are for your (Arch)Diocese, and contact the school you plan on attending to maximize the amount of your financial aid.
In addition to other scholarships and grants, Gonzaga University provides each undergraduate seminarian a 35% tuition discount (this does not apply to graduate school tuition).
