The difference between an MLS and an MPP is focus: a Master of Legal Studies (MLS) builds expertise in law, regulation, and compliance, while a Master of Public Policy (MPP) builds expertise in analyzing, designing, and evaluating public policy. An MLS suits professionals who apply legal rules within an organization, and an MPP suits professionals who shape policy in government, nonprofits, and research. Both take roughly one to two years, and neither qualifies a graduate to practice law.
An MLS and an MPP both appeal to professionals working near government and regulation, which is why they are often compared. The distinction comes down to whether you want to interpret and apply the law as it exists, or analyze and influence the policy behind it. This guide compares the two degrees on focus, skills, careers, and which fits which goal.

What Is an MLS?
A Master of Legal Studies is a graduate law degree for non-lawyers who need to understand and apply the law in their careers. MLS students study U.S. law, regulation, and compliance, then specialize in an area such as healthcare, HR, or technology. The degree builds legal literacy without leading to bar licensure. For a full breakdown, see our guide to what a Master of Legal Studies is.
What Is an MPP?
A Master of Public Policy is a graduate degree that trains professionals to analyze and shape public policy. MPP students study economics, statistics, program evaluation, and political institutions, and they learn to assess how policies are designed and whether they work. The MPP is the standard credential for policy analysts, program evaluators, and leaders in government, think tanks, and nonprofits.
The Key Differences Between an MLS and an MPP
Focus
The core difference is law versus policy. An MLS develops command of the legal rules and regulations that govern organizations, while an MPP develops command of how policy is analyzed, designed, and evaluated. One applies the law; the other shapes the policy behind it.
Skills
An MLS and an MPP build different toolkits. An MLS emphasizes legal reasoning and regulatory interpretation, while an MPP emphasizes quantitative analysis, economics, and program evaluation. A professional who needs to read regulations gains more from the MLS, and a professional who needs to analyze policy outcomes gains more from the MPP.
Careers
An MLS and an MPP lead toward different roles. MLS graduates advance in compliance, risk, regulatory affairs, and corporate or healthcare settings, while MPP graduates work as policy analysts, program evaluators, and government or nonprofit leaders. The MLS leans corporate and regulated industry, and the MPP leans public sector and policy.
Which Degree Should You Choose?
Choose an MPP if you want to analyze, design, or evaluate public policy in government, think tanks, or nonprofits. Choose an MLS if you want to interpret and apply law and regulation inside an organization, such as in compliance, risk, or regulatory affairs. The MLS is the better fit for professionals who work within regulatory frameworks, and the MPP is the better fit for those who want to shape them.
