Think Tank Internships and Fellowships in the US

Think tank internships and fellowships represent structured entry points into policy research and analysis across Washington, D.C. and major US metropolitan centers. This page covers how these programs are defined, how the application and selection processes function, the distinct program types candidates encounter, and the factors that determine which path fits a given professional or academic background. Understanding the differences between program formats matters because compensation structures, duration, and post-program outcomes vary substantially across institutions and ideological orientations.

Definition and scope

Think tank internships and fellowships are time-limited appointments through which individuals conduct policy research, contribute to publications, attend congressional briefings, and develop professional networks within the policy community. The major US think tanks directory includes institutions such as the Brookings Institution, the RAND Corporation, the Heritage Foundation, the Center for American Progress, and the Cato Institute — all of which operate formal internship or fellowship programs.

The distinction between an internship and a fellowship carries practical weight:

Some institutions use hybrid designations — "research assistantship," "visiting scholar," or "junior fellow" — that blend elements of both. The think tank scholar vs fellow distinction clarifies where these roles sit within an organization's hierarchy.

The scope of these programs spans virtually all major policy areas: national security, health policy, economic research, environmental regulation, technology governance, and foreign affairs. Ideological orientation of the host institution shapes the research agenda, as documented on pages covering top conservative think tanks, top progressive think tanks, and nonpartisan think tanks.

How it works

The application process at most large think tanks involves a written application, at least one writing sample of 5–20 pages, two to three letters of recommendation, and a structured interview. Brookings, for instance, runs a centralized application portal through which candidates apply to specific research programs rather than to the institution as a whole.

Once selected, interns and fellows are typically embedded within a specific program or center — the Hamilton Project at Brookings, the Economic Studies division, or the Foreign Policy program — rather than a generalist pool. Daily responsibilities include literature reviews, data analysis, drafting policy briefs, and supporting senior researchers preparing congressional testimony.

Fellowship programs with longer durations often include a formal deliverable: a working paper, a policy brief for external publication, or a chapter contribution. The RAND Corporation's Pardee RAND Graduate School combines doctoral study with embedded policy research, representing the most institutionally integrated model in the US think tank sector.

Compensation models follow three patterns:

  1. Unpaid internships — Found at smaller or budget-constrained organizations; legally permissible under Department of Labor primary beneficiary test guidelines for educational programs.
  2. Paid internships — Hourly or weekly wages; Heritage Foundation and Center for American Progress both post paid undergraduate internship opportunities.
  3. Stipended fellowships — Fixed monthly payments, typically ranging from $2,000 to $6,000 per month for mid-career positions, though specific figures vary by institution and funding source.

Common scenarios

Three distinct candidate profiles characterize the internship and fellowship pipeline:

Undergraduate students apply to summer internship cohorts, typically competitive 10–12 week programs aligned with the academic calendar. The Wilson Center's Congressional Fellowship and the White House Fellows program are adjacent pathways that intersect with the think tank world.

Graduate students and doctoral candidates pursue research fellowships that align dissertation work with institutional priorities. RAND, Brookings, and the Urban Institute all host doctoral-level researchers whose university affiliation remains active during the fellowship period.

Mid-career professionals — including former government officials, military officers, and senior practitioners — enter through named fellowship programs. These often carry explicit connections to the revolving door between government service and policy research roles. The Council on Foreign Relations International Affairs Fellowship is one well-documented example designed specifically for professionals with 8–12 years of experience.

Across all three scenarios, the host institution's funding model shapes the research agenda available to fellows, a dynamic examined in detail on how think tanks are funded.

Decision boundaries

Candidates face four substantive decisions when evaluating think tank programs:

  1. Paid vs. unpaid — Unpaid positions create access barriers and correlate with less socioeconomically diverse cohorts; paid programs at well-resourced institutions carry a demonstrated advantage for candidates without independent financial support.
  2. Partisan vs. nonpartisan — Completing a fellowship at an explicitly ideological institution (Heritage, CAP, Cato) signals alignment to future employers in government, advocacy, and media. Nonpartisan placements (Brookings, Urban Institute, RAND) signal methodological credibility across political contexts.
  3. Short-term vs. long-term — A 10-week summer internship builds network contacts and one publication credit; a 12-month fellowship typically produces a substantive research output suitable for academic or government audiences.
  4. Washington-based vs. distributed — The majority of consequential policy fellowships remain physically concentrated in Washington, D.C., where proximity to congressional staff and agency personnel enables the briefing and consultation activities that define how think tanks influence policy. A smaller cluster of programs operate from New York, Chicago, and university towns.
