The National Academy of Sciences is a private, nonprofit, self-perpetuating society of
distinguished scholars engaged in scientific and engineering research, dedicated to the
furtherance of science and technology and to their use for the general welfare. Upon the
authority of the charter granted to it by the Congress in 1863, the Academy has a mandate
that requires it to advise the federal government on scientific and technical matters. Dr.
Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of
the National Academy of Sciences, as a parallel organization of outstanding engineers.
It is autonomous in its administration and in the selection of its members, sharing with
the National Academy of Sciences the responsibility for advising the federal government.
The National Academy of Engineering also sponsors engineering programs aimed at
meeting national needs, encourages education and research, and recognizes the superior
achievements of engineers. Dr. Charles M. Vest is president of the National Academy of
Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences
to secure the services of eminent members of appropriate professions in the examina-
tion of policy matters pertaining to the health of the public. The Institute acts under the
responsibility given to the National Academy of Sciences by its congressional charter to
be an adviser to the federal government and, upon its own initiative, to identify issues of
medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute
of Medicine.
The National Research Council was organized by the National Academy of Sciences in
1916 to associate the broad community of science and technology with the Academy's
purposes of furthering knowledge and advising the federal government. Functioning in
accordance with general policies determined by the Academy, the Council has become
the principal operating agency of both the National Academy of Sciences and the Na-
tional Academy of Engineering in providing services to the government, the public, and
the scientific and engineering communities. The Council is administered jointly by both
Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest
are chair and vice chair, respectively, of the National Research Council.

Acknowledgments
The work of this panel has been immeasurably assisted by the insight and
counsel of numerous colleagues. In particular, we wish to acknowledge the
reviewers. This report has been reviewed in draft form by individuals chosen
for their diverse perspectives and technical expertise, in accordance with pro-
cedures approved by the Report Review Committee of the National Research
Council (NRC). The purpose of this independent review is to provide candid and
critical comments that will assist the institution in making its published report
as sound as possible and to ensure that the report meets institutional standards
for objectivity, evidence, and responsiveness to the study charge. The review
comments and draft manuscript remain confidential to protect the integrity of the
deliberative process. We wish to thank the following individuals for their review
of this report: Julian Betts, Department of Economics, University of California,
San Diego; William G. Bowen, President's Office, Andrew W. Mellon Foun-
dation; Pat Callan, President's Office, Higher Education Policy Institute, San
Jose, California; Charles T. Clotfelter, Center for the Study of Philanthropy and
Voluntarism, Duke University; Don E. Detmer, University of Virginia School of
Medicine; David N. Figlio, Institute for Policy Research, Northwestern Univer-
sity; Brent R. Hickman, Economics Department, University of Chicago; Michael
McPherson, President's Office, The Spencer Foundation; B. Don Russell, Jr.,
Department of Electrical Engineering, Texas A&M University; and Burton A.
Weisbrod, Institute for Policy Research, Northwestern University.
The review of this report was overseen by Greg Duncan, distinguished pro-
fessor of education, University of California, Irvine, and Charles Manski, Board
of Trustees professor in economics, Northwestern University. Appointed by the
NRC's Report Review Committee, they were responsible for making certain that

an independent examination of this report was carried out in accordance with
institutional procedures and that all review comments were carefully considered.
Although the reviewers have provided many constructive comments, and
improved the content of the report a great deal, they were not asked to endorse
the conclusions or recommendations; nor did they see the final draft of the report
prior to its release. Responsibility for the final content of this report rests entirely
with the authoring panel and the institution.
Many others generously gave of their time in offering oral presentations at
meetings and answering questions from panel members and staff, thereby helping
us to develop a clearer understanding of key issues relevant to the measurement
of higher education productivity and related issues. The panel thanks Lumina
Foundation; they provided financial support for the project and, even more impor-
tantly, helped shape the scope of the study. From Lumina, Jamie Merisotis, Kevin
Corcoran, Suzanne Walsh (now with the Bill & Melinda Gates Foundation), and
Charles (Chip) Hatcher provided insights and guidance in their roles as initiators
of the project. Kristin Conklin (HCM Strategists, LLC) kept the panel informed
about Lumina grantees' programs to increase productivity and proposals for
measuring the effectiveness of those efforts. The panel benefited from the open
discussion of these initiatives.
During meetings and deliberations, the panel heard from a number of subject
matter experts. Andrea Bonaccorsi, University of Pisa, Italy; Kevin Carey, New
America Foundation; Hamish Coates, Australian Council for Education Research;
Bo Hansson, OECD; Jorge Klor de Alva, University of Phoenix; and Donna
Sundre, James Madison University informed the panel about efforts to measure
higher education productivity, to design and implement accountability systems,
and to improve input/output data at different levels of aggregation.
The panel could not have conducted its work without an excellent and well-
managed staff. Connie Citro, director of the Committee on National Statistics,
and Stuart Elliott, director of the Board on Testing and Assessment, provided
expert guidance to the panel about the NRC study process. Program associate
Michael Siri provided excellent administrative, editorial, and research support.
Esha Sinha, program officer, provided valuable research and analytic assistance
with her understanding of higher education data sources. Her knowledge proved
especially helpful as we worked through some of the thornier measurement
issues. The panel also benefited from the work of Kirsten Sampson-Snyder,
Division of Behavioral and Social Sciences and Education, who was responsible
for overseeing the review process. Amy Smith provided able editing of numer-
ous drafts.
Christopher Mackie, the panel's study director, organized our meetings and
facilitated communication among panel members, including a lengthy process of
chapter revisions. His work required synthesizing and evaluating many disparate
points of input, seeking what common ground could be found, and guiding the
panel through careful discussion of the points of disagreement. He helped to

develop the structure for the panel's final report, and he shepherded the report
through the final review process.
Most importantly, the members of the panel deserve thanks for their patience,
creativity, and hard work. There is a reason that higher education productivity is
not currently reported in the national accounts. Reaching agreement on concep-
tual and measurement issues was difficult work. This report reflects the collec-
tive expertise and commitment of the individual members of the panel, each of
whom brought a unique perspective based upon a scholarly discipline, research
experience, and a lifetime of practice. Members were generous with their time
and effort, and they struggled to understand and appropriately acknowledge the
critical views of others. Our meetings provided many opportunities for panel
members to learn from one another.
