Extant Data Sources
• National Center for Education Statistics (NCES) Integrated Postsecondary Education Data System (IPEDS) – Comprehensive
– Includes masters and doctoral level data
– 537 possibly eligible institutions (89%)
– 236 institutions with only one GSS eligible program

Extant Data Sources - Limitations
• Limitations of IPEDS – No postdoctoral data
– Cannot determine practitioner vs. research programs
• All other sources – Merging the data

GSS Frame Updating - Results
• 605 institutions identified
• Graduate degree in only one GSS-eligible field (roughly 44%)
• 68 institutions from the remaining sources
• New Institution Pilot Study
