National Academies of Sciences, Engineering, and Medicine

The National Academies of Sciences, Engineering, and Medicine hold a position in American science policy that has no precise parallel: congressionally chartered since 1863, privately operated, funded primarily by federal contracts, and producing scientific consensus studies that carry extraordinary weight in regulatory and legislative debates — without any authority to compel anyone to do anything. When the FDA wants independent expert review of a vaccine safety question, when Congress needs to know whether nuclear waste storage at Yucca Mountain is scientifically sound, when EPA must justify its particulate matter standard in court, an Academy report provides the credibility layer that neither agency scientists nor industry-funded research can match. This influence-without-authority model has made NASEM the most trusted scientific institution in American government — and also one of the most strategically important to understand for anyone trying to shape or understand federal science policy.

Structure & Legal Status

Legal Authority

• 20 U.S.C. § 1863 — Charter of the National Academy of Sciences (1863 act): incorporates NAS; authorizes it to investigate, examine, and experiment on scientific subjects referred to it by government departments; requires NAS to report to requesting departments
• 20 U.S.C. § 1864 — Charter requires NAS members to serve without compensation from the United States; NAS may accept private funds for its charter activities
• 20 U.S.C. § 1881a — National Academy of Medicine establishment: authorizes the creation of an Institute of Medicine (renamed NAM in 2015) under the National Academies umbrella; same charter privileges apply
• FACA exemption: 5 U.S.C. App. 2, § 3(2) excludes from FACA's definition of "advisory committee" any committee "composed wholly of full-time, or permanent part-time, officers or employees of the Federal Government." Courts have held NASEM committees are separately exempt because they operate under a specific congressional charter that predates and supersedes FACA.

Key Mechanics

NASEM conducts consensus studies on assignment from federal agencies and congressional committees, producing reports that represent the best available scientific judgment of expert panels assembled specifically for each question. The process is designed to insulate conclusions from sponsor influence: the sponsoring agency pays for the study but cannot control its conclusions or delay publication. A typical study takes 18–24 months; an independent panel of 10–20 experts (chosen for expertise and vetted for conflicts of interest) reviews evidence, deliberates, and issues a report that must pass NASEM's own independent Report Review Committee before publication. Reports are not binding — Congress and agencies can ignore them — but they carry normative authority that shapes regulatory justifications, litigation records, and legislative debates. NASEM is exempt from FACA (Federal Advisory Committee Act), which would otherwise require open meetings and public documentation; NASEM committees operate under their private congressional charter, which predates FACA. NASEM is funded ~85% by federal agency contracts (study fees) and ~15% by endowment and private sources; it is not a federal agency and its employees are private-sector workers. Members of the National Academies are elected by peer vote — election to NAS, NAE, or NAM is considered the highest honor in American science — and serve without pay from the government.

History

1863: President Lincoln signed the Act to Incorporate the National Academy of Sciences on March 3, 1863 — the last night of the 37th Congress, two years into the Civil War. The founding motivation was practical: the Navy Department was flooded with inventors pitching weapons and equipment; Congress wanted a scientific body that could evaluate proposals and advise government without the process becoming political. The 50 founding members included Louis Agassiz and Benjamin Peirce.

1916: NAS established the National Research Council (NRC) to mobilize scientific expertise for World War I. The NRC became the permanent operating arm for studies and reports — most NASEM reports are formally "Reports of the National Academies" issued through the NRC.

1964: Congress established the National Academy of Engineering by separate act. Engineering was excluded from the NAS charter because its founders intended NAS as a pure science body.

1970: Institute of Medicine established under the National Academies charter to provide independent scientific advice on health and medicine policy. Renamed the National Academy of Medicine in 2015.

How Consensus Studies Work

The NASEM consensus study process is the institution's most important and most misunderstood product:

1. Commissioning: A federal agency or committee of Congress requests a study and pays NASEM's costs (typically $800,000–$2,000,000 per study, depending on complexity). The study charge — the specific questions to be answered — is negotiated between the sponsor and NASEM's program staff.

2. Committee formation: NASEM staff identify 12–20 volunteer experts whose knowledge spans the study charge. Each nominee is screened for conflicts of interest; anyone with a financial relationship to entities that would benefit from particular findings must disclose and may be excluded. The committee is constituted to reflect the range of scientific opinion on the question, not to reach a predetermined conclusion.

3. Information gathering: The committee holds public sessions where it hears testimony from stakeholders, agency staff, affected parties, and other experts. Additional information is gathered through commissioned papers and staff research.

4. Deliberation and drafting: Committee deliberations are closed (not subject to FACA's open-meeting requirement). The committee drafts its report through internal discussion; findings require consensus, though individual members may write minority views.

5. Independent review: Before publication, each NASEM report is reviewed by an independent group of experts (the Report Review Committee, a standing body). Reviewers check that findings are supported by evidence and that the committee addressed its charge. The committee must respond to all reviewer comments; the final report must satisfy the Report Review monitor.

6. Publication: Reports are published by the National Academies Press, available free online. The publication process typically takes 12–18 months from commissioning to release.

7. No binding authority: NASEM reports are advisory only. The agency that commissioned the study is not required to follow the recommendations. But in practice, agencies that commission studies and then ignore them face significant political and legal risk — in regulatory litigation, courts look at whether agencies addressed independent scientific reviews of their rules.

What NASEM Reports Do

Regulatory foundation: EPA's National Ambient Air Quality Standards for particulate matter and ozone are regularly reviewed by NASEM's Clean Air Scientific Advisory Committee (CASAC). FDA uses NASEM panels to review the scientific basis for drug approvals in contested areas. NRC (Nuclear Regulatory Commission) commissions NASEM reviews of nuclear waste management science.

Congressional agenda-setting: NASEM reports can create political momentum for legislative action. The 1999 IOM report on medical errors ("To Err is Human") estimated 44,000–98,000 preventable hospital deaths annually — it created the patient safety movement and shaped subsequent federal patient-safety legislation.

Agency dispute resolution: When agencies disagree with industry or advocacy groups about the scientific basis for a regulation, commissioning an NASEM study allows the agency to point to an independent source. The report doesn't end the dispute, but it shifts the burden.

FACA exemption significance: Because NASEM committees are not subject to FACA, they have flexibility that federal advisory committees do not: they can include members with significant industry or academic affiliations (within conflict-of-interest limits), hold closed deliberations, and control their own membership without the "balanced representation" requirements FACA imposes. This makes NASEM committees more scientifically rigorous but also more susceptible to the critique that they reflect scientific establishment consensus rather than the full range of views.

NAS Membership and Election

Election to the National Academy of Sciences is the highest honor the U.S. scientific community bestows on its own members. Approximately 100 new members are elected each year by current members, based on distinguished and continuing achievement in original research. Membership is for life and carries no compensation.

The election process is internal — nominations are made by existing members, evaluated by section committees, and voted on by the full membership. There is no external review or government approval. This self-governance is central to the Academy's claim to scientific independence.

Internationally, NAS participates in the InterAcademy Partnership — the global network of national academies that produces joint statements on global science policy questions.

How It Affects You

If you are a citizen or consumer: When federal agencies make major health or environmental decisions — acceptable levels of pollution, food safety standards, vaccine schedules — those decisions are often grounded in NASEM consensus reports. The quality of those reports directly affects the standards that govern your environment and health.

If you are a researcher or academic: NASEM membership is the pinnacle of recognition in U.S. science. If your work has potential policy relevance, federal agencies may commission NASEM to produce a report that your work influences. NASEM also offers fellowship programs and serves as a convening organization for scientific discussion.

If you work at a federal agency: Commissioning an NASEM study is a strategic decision — it buys time, builds scientific credibility, and creates a legal record for regulatory action. Understanding when NASEM studies help (establishing scientific consensus) versus when they slow you down (when you already have consensus and need action) is a key regulatory strategy skill.

If you are a journalist, researcher, or policy analyst: All NASEM reports are publicly available free at nap.nationalacademies.org. Committee rosters, study charges, and public hearing transcripts are public. The Report Review process documentation is not public (to protect reviewer candor), but completed reports include a response to reviewers section.
