Taulbee in Depth: Department Space per Faculty Member


Every three years, the CRA Taulbee Survey asks a set of Department Profiles questions including questions about department space. In the full Taulbee report published in CRN in May 2013, we reported on the space data collected in fall 2012. Tables in that report provided percentiles for department space in the categories of total space, offices, conference and seminar rooms, research labs, and instructional labs. The percentiles were across all departments of a given type (US CS Public, US CS Private, US CE, US Information, and Canadian) without regard for the size of the department. However, department size is clearly a major determiner of space.

To allow departments to better compare their own space allocations to the overall Taulbee numbers, this analysis reports on space per faculty member in two ways: by number of tenured and tenure-track faculty, and by number of tenured and tenure-track faculty plus number of research faculty and postdocs. Those values were computed for each department; percentiles of the normalized space for all US departments and for each type of department are given in tables Space1 through Space6.

The total space per tenured or tenure-track faculty member varies little across the US department types; the median value ranges from 1,141 (US CS private) to 1,297 square feet (US Information). Space allocation, however, varies. Not surprisingly, Computer Engineering departments have the highest median per capita research lab space at 442 square feet, while Information has the lowest at 62. Computer Engineering likewise has a higher median per capital square footage for instructional lab space at 242, while the US CS and Information programs range from 128 to 185.

There is substantially more variation in per capita total space across departments and across department types at the 90th percentile. There’s no clear pattern for these departments; some are small and some large, and some are colleges of computing or information rather than individual departments, but some are not. Probably the variation represents some type of “other” space.

Table Space7 offers a different way of looking at space allocation. For each department, the percent of total space represented by offices, conference and seminar rooms, research labs, and instructional labs was computed. The table shows percentiles of these percents; for example, the median of space allocated to offices is 41%, and the median of space allocated to research labs is 23%.
