Note: Faculty numbers are counts of full-time A&S faculty excluding Arts, SIPA, and SPS (that is, Humanities + Natural Sciences + Social Sciences). These are the most relevant faculty numbers, as they count those faculty who normally teach full-time undergraduates. Student numbers are FTEs of students in the A&S colleges, namely CC + GS.
