Again, you guys are looking at inconsistent data whenever you try to compare schools. The IPEDs data is notoriously unreliable because its expense categories are not applied uniformly.
For example, here the ipeds results for Amherst and Swarthmore, expressed as per student spending in Fiscal Year 2006:
Code:
Chart/Indicator Amherst Swarthmore
Instruction $20,472 $25,972
Research $2,085 $2,233
Public service $0 $997
Academic support $8,813 $9,598
Institutional support $9,212 $13,866
Student services $8,534 $7,634
Other core expenses $854 $0
$49,970 $60,300
According to this, Swarthmore spent $10,000 more per student despite having virtually identical per student endowments. That's just pure baloney. In fact, a quick glance at the actual annual financial reports for the two schools shows that they both spent between $71k and $73k per student that year. Obviously, ipeds is not capturing all the spending -- we can see that from the fact that they show Amherst spending zero on public service, which is not the case.
A quick look at actual expense items from the two annual reports shows the problem. They don't use the same categories.
Swarthmore:
Instruction 41,540,000
Academic support 15,139,000
Student services 10,336,000
Institutional support 23,684,000
Auxiliary activities 20,298,000
Research and public service 3,664,000
Total expenses 114,661,000
Amherst:
Instruction and academic programs 31,538,336
Academic and student services 18,408,380
Library 6,466,098
Research and public programs 5,951,806
Operation and maintenance of plant 13,083,272
Administrative and general 16,252,623
Pensions and professional fees 332,198
Academic prizes, fellowships and awards 1,402,459
Auxiliary activities 16,034,856
Interest expense 5,425,303
Other 1,513,327
Total expenditures 116,408,658
Remember, the IPEDS instructions say NOT to include maintenance of the plant if accounted for as a separate line item, so Amherst doesn't. Swarthmore doesn't account for this as separate line item. It is included in the Institutional Support category, both in the Annual Report and the IPEDs data.
Likewise, where is the library in the Amherst IPEDS data? Probably not there, since Amherst reports it as a separate line item (it has a separate endowment). Swarthmore's library expenses likely fall under Academic Support (operations) and Institutional Support (maintenance, carpet cleaning, electricity, and so forth).
Likewise, I'm sure that the $10 million difference in instructional spending reflects different accounting buckets, not an actual difference in magnitude of instructional cost at Amherst and Swarthmore.
Nobody in college higher education finance puts any faith in the IPEDS categories for institutional comparisons. It's never apples versus apples.
