nec = not elsewhere classified.
a In 2007, eligible fields were reclassified, newly eligible fields were added, and the survey was redesigned to improve coverage and coding of eligible units. 2007 data presented in this table are the data collected in 2007, which were labeled as "2007new" in the past publications. See appendix A in http://www.nsf.gov/statistics/nsf10307/ for more detail on the changes made in 2007.
b Beginning with 2008, more rigorous follow-up was done with institutions regarding the exclusion of practitioner-oriented graduate degree programs in Psychology and in Other health (a subfield of health). This change may affect interpretation of trends in these fields.
