In summary

Public policy and public administration are neighboring applied fields that share faculty, journals and often the same graduate school, and the shortest honest distinction is by the question each asks. Public policy asks what government should do about a problem, and whether what it did worked: defining the problem, comparing options against explicit criteria, projecting consequences and evaluating results. Public administration asks how a public program is organized, managed and delivered: structures, budgets, people, procurement, accountability and performance. A common shorthand is that policy decides what and administration determines how. The shorthand is a teaching device, not a boundary in the real world. The textbook separation of the two has been challenged for well over a century, because the people who implement a program inevitably shape it: frontline workers exercise discretion, agencies write the detailed rules that give statutes their meaning, and implementation experience feeds back into the next round of policy. That is why schools of public affairs commonly teach the two together, why the Master of Public Policy (MPP) and Master of Public Administration (MPA) have overlapping cores, and why one accreditor, NASPAA, reviews master's programs in both under a single set of standards. Choose by the question you need answered. If you are weighing options, estimating effects or judging whether a program achieved its goals, you are doing policy analysis or evaluation, and the toolkit is economics, statistics and causal inference. If you are running, budgeting, staffing or auditing a program, you are doing public administration, and the toolkit is organizational and management methods plus public finance and law. For research administrators the two meet directly in grants: a federal award is a public program, the rules in 2 CFR 200 are the administrative machinery behind it, and the requirements that appear on an award began life as policy decisions.

How do Public policy, Public administration compare side by side?

The table below compares Public policy, Public administration across 12 procurement-relevant dimensions, from definition through overlap and when to use which.

Side-by-side comparison

Dimension	Public policy	Public administration
Definition	The study of how governments and other public institutions decide what to do about collective problems, how those decisions are carried out, and whether they work. The word also names the thing studied: a statute, regulation, budget allocation or standing practice adopted by a public authority to address a problem.	The study and practice of organizing, managing and carrying out the work of government and of the nonprofit and contracted organizations that deliver public services. It begins where a legislature decides a program should exist and covers everything that has to happen next.
Core question	What should government do about this problem, why, and did it work? The emphasis is on choosing among options and judging results.	How should this program be organized, funded, staffed, run and held to account? The emphasis is on institutions, operations and delivery.
Primary focus	Problem definition and agenda setting, design and choice of policy instruments, evaluation and learning, and the politics and institutions that make options feasible.	Organization and structure, public budgeting and financial management, human resources, performance management, accountability and ethics, service delivery, procurement and intergovernmental relations.
Orientation	An applied, interdisciplinary field oriented toward decisions, drawing on political science, economics, statistics, law, sociology and management.	An applied field and profession oriented toward institutions and operations, in which many influential ideas came from practitioners.
Typical methods	Policy analysis (problem, criteria, alternatives, projected outcomes, recommendation); program evaluation; causal inference with observational data; randomized and field experiments; microsimulation; benefit-cost and cost-effectiveness analysis.	Organizational and management methods: surveys of employees and citizens, analysis of administrative and budget data, case studies and process tracing, interviews and document analysis, network analysis, and mixed methods. Program evaluation is shared with policy.
Typical work and employers	Policy analysts, evaluators and researchers in legislative and executive branches, think tanks, evaluation firms, research institutes, international organizations, foundations and universities.	Program and budget analysts, city and county managers, grants and contracts managers, performance and evaluation officers and nonprofit executives in agencies, public authorities, nonprofits, healthcare systems and universities.
Typical master's degree	Master of Public Policy (MPP), which weights analytic and quantitative training more heavily: microeconomics, statistics, policy analysis and program evaluation, with a specialization and a client project.	Master of Public Administration (MPA), which prepares students for management and leadership: public management, budgeting and finance, human resources, analysis, ethics and law, with a capstone or internship. Some schools offer a Master of Public Affairs covering both.
Accreditation	In the United States, the Network of Schools of Public Policy, Affairs, and Administration (NASPAA) accredits many MPP programs. Accreditation is a quality signal, not a legal requirement for public employment.	NASPAA is the recognized global accreditor of master's programs in public administration as well as public policy and public affairs, under the same set of standards. Requirements vary by employer and country.
Grants administration touchpoints	Policy explains where award requirements come from: cost principles, data-sharing, public-access, research-security and conflict-of-interest rules are policies with identifiable origins and revision cycles. Funders themselves are policy instruments.	Administration is the machinery that applies those requirements: the Uniform Guidance at 2 CFR 200 (pre-award requirements, cost principles, procurement standards, audit requirements), the single audit, subawards and internal controls. Managing a federal grant is a form of public administration.
Professional societies and journals	Association for Public Policy Analysis and Management (APPAM), which publishes the Journal of Policy Analysis and Management. Other outlets include Policy Sciences, the Policy Studies Journal and the Journal of Public Policy.	American Society for Public Administration (ASPA), which publishes Public Administration Review and Public Integrity. Other outlets include the Journal of Public Administration Research and Theory and Public Management Review. APPAM also serves the policy-and-management community.
Who funds the research	Federal research agencies, mission agencies that commission evaluations, and private foundations; examples in CASRAI's reference pages include the William T. Grant Foundation and the Spencer Foundation. Programs and eligibility change, so verify current solicitations.	Funding is diffuse: science agencies support some basic research on institutions and organizations, mission agencies commission evaluations and applied studies, and foundations support work on public service and evidence use. Verify current solicitations with each funder.
Overlap and when to use which	Overlap is heavy: both use program evaluation, share faculty and degree cores, and meet in implementation research. Use "public policy" when the question is which option to choose or whether a policy worked.	Use "public administration" when the question is how to run, staff, budget, procure or audit a program, or how to hold it accountable. When the question spans both, as in a program redesign, expect to use both.

Common questions

Common questions about Public policy vs Public administration

What is the difference between public policy and public administration?

Public policy focuses on deciding what to do about public problems and evaluating results; public administration focuses on organizing, managing and delivering public programs. A common shorthand is that policy decides what and administration determines how. The two overlap heavily and are often taught together, and the separation has been challenged for over a century because implementers shape the policies they carry out.

Is an MPP or an MPA better?

Neither is better in general; they weight different skills. An MPP puts more weight on analytic and quantitative training such as economics, statistics and policy analysis, while an MPA puts more on management and leadership such as budgeting, human resources and ethics. Core courses overlap, many schools offer both, and requirements for a given job depend on the employer. A degree from an accredited program is a quality signal, not a legal requirement for public employment.

What is NASPAA, and does it accredit both?

NASPAA, the Network of Schools of Public Policy, Affairs, and Administration, is the recognized global accreditor of master's degree programs in public administration, public policy, public affairs and related fields. It reviews programs against a single set of standards, which reflects how closely the fields are linked. It is an accreditor and membership organization for schools rather than for individuals.

Where do public policy and public administration meet in grants management?

A federal or state grant is a public program, so administering it is public administration in practice, while the requirements attached to it began as policy decisions. In the United States the central rulebook for federal awards is the Uniform Guidance at 2 CFR 200, whose parts address pre-award requirements, cost principles, procurement standards and audit requirements. Understanding the policy process helps an office anticipate change; understanding administration helps it interpret and apply the rules.

Which professional society should I join, APPAM or ASPA?

It depends on where your work sits. The Association for Public Policy Analysis and Management (APPAM) is the natural home for researchers at the policy-analysis end and publishes the Journal of Policy Analysis and Management. The American Society for Public Administration (ASPA) is a professional membership association for public service and publishes Public Administration Review. Many people in applied roles follow the literature of both.

How do political science and economics relate to each of them?

Political science asks why governments and political actors behave as they do, and economics asks how people and markets respond to incentives. Public policy takes both, plus statistics, law, sociology, psychology and management, and points them at a concrete decision. Public administration draws on political science for questions of institutions and accountability and on management research for organizational questions.

Is public management the same as public administration?

Often, in everyday use. Public management is usually the more managerial, performance-oriented strand of public administration, covering budgeting, human resources, strategic planning and performance measurement. In scholarship the terms overlap heavily, and degree programs and journals use them almost interchangeably. Note that "administration" can also mean an executive term of office; here it means the management of public programs and organizations.
