Preface
Preface
The Association of Community College Trustees (ACCT) contracted with the
authors in 1999 to create the model used in this study. The original vision
was simple—to make available to colleges a generic and low cost yet
comprehensive tool that would allow them to estimate the economic benefits
accrued by students and taxpayers as a result of the higher education
achieved. In short: it only makes economic sense for the students to attend
college if their future earnings increase beyond their present investments of
time and money; likewise, taxpayers will only agree to fund colleges at the
current levels or increase funding if the economic benefits exceed the costs.
An important requirement of the ACCT vision was that the model reach
beyond the “standard” study—the computation of the simple multiplier
effects stemming from the annual operations of the colleges. Although the
standard study was part and parcel of the model ultimately developed, it was
only a relatively small part. The current model also accounts for the economic
impacts generated by past students who are still applying their skills in the
local workforce; and it accounts for a number of external social benefits such
as reduced crime, improved health, and reduced welfare and unemployment,
which translate into avoided costs to the taxpayers. All of these benefits are
computed for each college and analyzed. To the extent possible, the analysis
is based on regional data adjusted to local situations.
Although the written reports generated for each college are similar in text,
the results differ widely. This, however, should not be taken as an
indication that some colleges are doing a better job than others in
educating the students. Differences among colleges are a reflection of the
student profiles, particularly whether or not the students are able to maintain
their jobs while attending, and the extent to which state and local taxpayers
fund the colleges. Some students give up substantial earnings while
attending college because employment opportunities are few and far
between. In other cases they are able to work while attending because the
area has an abundance of opportunities. That the average student rate of
return of 15% for college A is different from the rate of return of 20% for
college B, therefore, does not mean that B is doing a better job than A. Rather,

it is attributable to the employment opportunities in the region, and to the
fact that one college may cater more to women than to men, or to minorities,
and/or to different kinds of students such as transfer, workforce or retired,
etc. In turn, the student body profiles are associated with their own distinct
earnings functions reflecting these employment, gender and ethnicity
differences. The location of the college, therefore, dictates the profile of the
student body, which, to a large extent, translates into the magnitudes of the
results. In this sense, it could well be that College A with a 15% student rate
of return is actually a better or more efficiently managed school than College
B with a 20% student rate of return. The qualitative difference in
management efficiency is not equal to the difference between the two returns.

INTRODUCTION
OVERVIEW
C
ommunity colleges (CCs) generate a wide array of benefits. Students benefit
directly from higher personal earnings and society at large benefits indirectly
from cost savings (avoided costs) associated with reduced welfare and
unemployment, improved health, and reduced crime. Higher education,
however, requires a substantial investment on the part of the students and
society as a whole. Therefore, all education stakeholders—taxpayers,
legislators, employers, and students—want to know if they are getting their
money’s worth. In this study, Southwest Texas Junior College (SWTJC)
investigates the attractiveness of its returns relative to alternative public
investments. The benefits are presented in three ways: 1) annual benefits, 2)
present values of future annual benefits (rates of return and benefit-cost
ratios, etc.), and 3) regional economic benefits.
The study has four chapters and two appendices. Chapter 1 is an overview of
the benefits measured. Chapter 2 details the major assumptions underlying
the analysis. Chapter 3 presents the main socioeconomic and regional
economic results. Finally, Chapter 4 presents a sensitivity analysis of some
key assumptions—tracking the changes in the results as assumptions are
changed. Appendix 1 is a short primer on the context and meaning of the
investment analysis results—the net present values (NPV), rates of return
(RR), benefit/cost ratios (B/C), and the payback period. Appendix 2 explains
how the earnings related to higher education data were derived.
ANNUAL PRIVATE AND PUBLIC BENEFITS
Private benefits are the higher earnings captured by the students; these are
well known and well documented in the economics literature. Less wellknown and documented is a collection of public benefits captured by society
at large, the indirect benefits, or what economists call positive externalities,
such as improved health and lifestyle habits, lower crime, and lower

incidences of welfare and unemployment. These stem from savings to
society from reduced burdens on taxpayer-provided services. The dollar
savings (or avoided costs) associated with reduced arrest, prosecution, jail,
and reform expenditures are estimated based on published crime statistics
arranged by education levels. Likewise, statistics that relate unemployment,
welfare, and health habits to education levels are used to measure other
savings. The annual economic impacts are presented in three ways: 1) per
credit-hour equivalent (CHE), defined as a combination of credit and noncredit attendance 1, 2) per student, and 3) in the aggregate (statewide).
PRESENT VALUES OF FUTURE BENEFITS
The annual impacts continue and accrue into the future and are quantified
and counted as part of the economic return of investing in education. This
lifetime perspective is summarized as present values–a standard approach of
projecting benefits into the future and discounting them back to the present.
The present value analysis determines the economic feasibility of investing in
CC education—i.e., whether the benefits outweigh the costs. The time
horizon over which future benefits are measured is the retirement age (65)
less the average age of the students.
The values of future benefits are also expressed in four ways: 1) net present
value (NPV) total, per CHE, and per student, 2) rate of return (RR) where the
results are expressed as a percent return on investment, 3) benefit/cost (B/C)
ratio—the returns per dollar expended, and 4) the payback period—the
number of years needed to fully recover the investments made (see
Appendix 1 for a more detailed explanation of the meaning of these terms).

Instruction hours are not the same as credit hours. CCs prepare people for jobs and are less concerned
with (ceremonial) degrees. Many attend for short periods and then leave to accept jobs without
graduating. Others simply enroll in non-academic programs. Nonetheless, the CHEs earned will
positively impact the students’ lifetime earnings and social behavior.

Chapter 1: Introduction
REGIONAL ECONOMIC BENEFITS
The benefits of a robust local economy are many: jobs for the young,
increased business revenues, greater availability of public investment funds,
and eased tax burdens. In this study we estimate the role of SWTJC in the
local community economy in terms of its share of total community earnings,
defined as indicated in Figure 1.1. In general, these CC-linked regional
earnings fall under two categories: 1) earnings generated by the annual
operating expenditures of the college, and 2) earnings attributable to the CC
skills embodied in the local workforce.

DATA SOURCES AND ASSUMPTIONS
INTRODUCTION
T
o the extent possible, documented statistics obtained from several databases
and from the colleges themselves are used to craft the assumptions on which
the results are based. In the few cases where hard data are scarce, however,
institutional researchers on the scene apply best judgments and estimations
on the basis of their intimate knowledge of the college and the student body.
This chapter contains six assumption sections, all based on various data
imbedded in the analytic model: 1) the SWTJC profile; 2) annual earnings by
education levels; 3) the social benefit assumptions (health, crime and
welfare/unemployment); 4) education costs; 5) other assumptions (the
discount rate used, health, crime, and welfare cost statistics, etc.); and 6)
assumptions pertaining to regional economic effects.
COLLEGE PROFILE
Faculty, Staff, and Operating Budget
SWTJC employed 230 full- and 103 part-time faculty and staff in year 2000
amounting to a total annual payroll of some $9.3 million. Table 2.1 shows
SWTJC‘s annual revenues by funding source: a total of $14 million. Two
main revenue sources—private and public—are indicated. Private sources
include tuition and fees (25.4%) plus 6.9% from other private sources (such as
contract revenues, interest payments and the like). Public funding is
comprised of local taxes (3.6%), state aid (43.3%), and federal grants (20.9%).
These budget data are critical in identifying the annual costs of educating the
CC student body from the perspectives of the students and the taxpayers
alike.

The Students
Students attend community colleges for different reasons: to prepare for
transfer to four-year institutions, to obtain Associate Degrees or Certificates,
obtain basic skills, or perhaps most importantly, to take refresher courses or
participate in non-credit programs. Students also leave for various reasons;
they may have achieved their educational goals or decided to interrupt their
college career to work full-time. Tables 2.2 – 2.4 summarize the student body
profile. The SWTJC unduplicated student body (headcount) is 3,668 (FY00-01
enrollment). This total consists of both credit and non-credit students.

Chapter 2: Data Sources and Assumptions
Some students forego earnings entirely while attending college while others
may hold part- or full-time jobs. Information about student employment
plays a role in determining the opportunity cost of education incurred by the
students while attending SWTJC2. Table 2.2 rows labeled: “% Employed
While Attending” and “% of Full-Time Earning Potential” provide the
percentage estimates of the students who held jobs (75%) while attending
SWTJC, and how much they earned (35%) relative to full-time employment
(or what they would statistically be earning if they did not attend SWTJC).
The former is a simple percent estimate of the portion of the student body
working full or part time. The latter is a more complex estimate of their
earnings relative to their earning power if they did not attend college (i.e.,
recognizing that several students may hold part time jobs working for
minimum wage while attending college).

As indicated in the table, it is estimated that 50% of the students remain in
the local community (as defined in Figure 1.1) and thereby generate local
community benefits. The remaining 50% leave the community and are not
counted as contributing to regional economic development. The 50% local
retention rate applies only to the first year, however. We assume that 65% of
the students, and associated benefits, will leave the area over the next 30
years due to attrition (e.g., retirement, out-migration, or death).
The opportunity cost is the measure of the earnings foregone; the earnings the individual would have
collected had he or she not attended SWTJC.

Chapter 2: Data Sources and Assumptions
The last five items in Table 2.2 are settling-in factors—the time needed by
students to settle into the careers that will characterize their working lives.
These factors are adapted from Norton Grubb (June 1999). Settling-in factors
have the effect of delaying the onset of the benefits to the students and to
society at large. Thus, we assume that for transfer track students, the earnings
benefits will be delayed for at least 2.5 years to account for the time spent
subsequently at 4-year colleges.
Entry-Level Education, Gender, and Ethnicity
Table 2.3 shows the education level, gender, and ethnicity of the SWTJC
student body. This breakdown is used only to add precision to the analysis,
not for purposes of comparing between different groups. Five education
entry levels are indicated in approximate one-year increments, ranging from
less than HS to post AD. These provide the platform upon which the
economic benefits are computed.
The entry level characterizes the education level of the students when they
first enter the college; this is consistent with the way most colleges keep their
records. The analysis in this report, however, is based on the educational
achievements of the students during the current year. As not all students
reported in the enrollment figures for the fiscal year are in their first year of
college, an adjustment was made to account for upper class students who
had accumulated credits during their community college experience and
moved up from the AD
