IPEDS publishes graduation rate, tuition, and admission rate for first-time undergraduates. Those numbers describe a bachelor's student well and a master's student not at all. So the bachelor's model weighs graduation rate (40%), in-state tuition (25%), delivery flexibility (20%), and selectivity (15%), while the master's model drops the undergraduate figures entirely and scores CAHME accreditation (40%), program size from IPEDS completions (35%), and delivery (25%). Doctoral programs are listed but not scored, and the methodology page says why.
The site also takes a clear position on the field's biggest blind spot. CAHME is the only accreditor of master's-level healthcare management programs recognized by the US Department of Education and CHEA, and only 103 of the 414 master's programs hold it. No bachelor's degree carries CAHME accreditation, because CAHME does not accredit at that level. The homepage explains both before it shows a single ranking.
