completions (48%) at the 1,185 Carnegie-classified non-doctoral granting units. Since the increase in the number of degree
completions at non-doctoral granting units is less than the increase in the number of degree completions at doctoral-granting units, it is not surprising that non-doctoral granting units
are less likely than doctoral-granting units to report they are experiencing a significant impact from increasing enrollments [ 2].
We note, however, that CS degree production at non-doctoral
granting institutions increased by almost 50% during the period
2009-2015 (see Figure 8), and Figure 6 suggests that this growth
in CS degree production at non-doctoral granting institutions
will continue to increase for the near future.
The CRA Enrollment Survey collected data from 134 doctoral-granting units, which is a substantial portion of the 313
Carnegie-classified doctoral-granting units in IPEDS. However, the CRA Enrollment Survey collected data from only 93
non-doctoral granting units, which is a small fraction of the
1,185 non-doctoral granting units in the IPEDS data. The IPEDS data represents a much wider variety of institutions than
the CRA Enrollment Survey data. The IPEDS institutions include small, medium, and large master degree programs; liberal arts bachelor degree programs; more specialized bachelor
degree programs; and other kinds of non-doctoral institutions.
DEGREE COMPLETIONS AT
PUBLIC VS. PRIVATE INSTITUTIONS
Figure 9 shows the total number of IPEDS CS degree completions at public and private institutions. The growth in total
completions from 2009 to 2015 was much larger for public institutions (79%) than private institutions (58%).
THE WIDESPREAD INCREASE IN NONMAJOR
In addition to the phenomenal increase in computer science
majors discussed previously, there is a large increase in the
number of nonmajors taking computing courses. Increases in
IPEDS DEGREE COMPLETION DATA
Comprehensive data from the Integrated Postsecondary Education Data System (IPEDS) on degree completions at CS and
CIS programs can improve our understanding of the CRA Enrollment Survey data, especially in relation to non-doctoral
granting institutions. The data provided in this section is from
the IPEDS Data Center on degree completions [ 4] for two Classification of Instructional Programs (CIP) codes—Computer and
Information Sciences, General ( 11.0101) and Computer Science
( 11.0701). The data is for all Carnegie-classified, not-for-profit,
4-year public and private institutions in the United States, Guam,
Puerto Rico, and the U.S. Virgin Islands. We looked at completions under both 11.0101 and 11.0701 since some institutions
with computer science degree programs report completions
under CIP code 11.0101, while others report completions under
11.0701. In this section, we use “CS” to represent reported completions under both 11.0101 (CIS, general) and 11.0701 (CS).
COMPARING IPEDS DATA TO THE
CRA ENROLLMENT SURVEY DATA
The CRA Enrollment Survey collected data from 134 doctoral-granting units and 93 non-doctoral granting units. To
compare the CRA Enrollment Survey data collected with IPEDS degree completions, we consider two groupings of Carnegie-classified institutions: ( 1) Highest, Higher and Moderate
Research Doctoral Institutions (Doctoral in Figure 8) and ( 2)
Large, Medium and Small Masters and Liberal Arts and Diverse
Baccalaureate Institutions (Non-Doctoral in Figure 8).
Figure 8 shows remarkable growth in CS completions (94%)
at the 313 Carnegie-classified doctoral-granting units from
2009 (which reflects growth in majors that began three years
earlier) to 2015. The IPEDS degree completion data is consistent with the substantial growth reported previously in this
article. Figure 8 also shows noteworthy growth in IPEDS CS
