One exception, however, is the MA in Grant Writing, Management and Evaluation program offered at Concordia University Chicago. Concordia's program takes an multidisciplinary approach to grant writing that includes collaboration with your student cohort and partnering with organizations relevant to your professional goals. The program is 100% online, requires 30 credit hours of coursework, and can be completed in 20 months. The cost is over $13,000, but unlike many graduate programs, financial aid is available.
