As massive open online courses (MOOCs) shift toward professional degree and certificate programs, can they become a global on-ramp for increasing access to emerging fields for underrepresented groups? This mixed-methods study addresses this question by examining one of the first MOOC-based blended professional degree programs, which admitted students to an accelerated residential master's program on the basis of performance in MOOCs and a proctored exam. We found that male students and students with master's degrees were more likely to complete the online program and the blended program had more male students and more students with master's degrees than students in the existing residential program. Students who enrolled in the blended graduate program earned higher average grades than students in the residential program earned in their in-person courses (3.86 vs 3.75, p < .01). The findings of this study provide an example of how new online learning models can serve particular niches, but may not address broader equity challenges.
