How Volunteers and Experts Contribute to the National Academies' Work

The National Academies of Sciences, Engineering, and Medicine rely on a large, distributed base of volunteers and experts to produce independent, objective advice. According to the organization, more than 20,000 volunteers, Academy members, and staff contributed to its mission in 2025, helping policymakers and the public understand and solve complex problems. If you want to understand how the institution actually functions — or how you might take part — the key is to see how individual experts are organized into committees, studies, and consensus reports rather than working as a single in-house body.

The basic model: advice assembled from outside experts

The Academies describe their purpose as "driving progress for the benefit of society by providing independent, objective advice to advance science, engineering, and medicine." That advice is not generated by a permanent staff alone. It is assembled by convening specialists from universities, industry, government, and other institutions who serve in a volunteer capacity.

This structure matters because it is what allows the Academies to claim independence: the people producing a report are not employees of the organization and are generally not paid for their committee service. Their expertise is the input; the institution provides the process, staff support, and review infrastructure.

How the work is organized

Committees and consensus studies

The core mechanism is the committee. A group of experts with relevant and complementary backgrounds is appointed to a specific question — for example, the scientific priorities for a field, or the safety implications of a new technology. The committee reviews evidence, hears from stakeholders, deliberates, and produces a consensus report. "Consensus" means the findings reflect the group's collective judgment, not a single author's view.

Decadal surveys and long-range planning

Some of the most visible outputs are decadal surveys, which set scientific priorities for a field over roughly ten years. The page evidence gives a concrete example: NASA announced it would begin preliminary design and technology development for the PRIMA far-infrared telescope, described as the first of a new class of telescopes recommended by a 2020 National Academies decadal survey that identifies scientific priorities and opportunities for astronomy and astrophysics. That is a direct illustration of expert volunteers shaping a federal agency's direction.

Convening across sectors

The contribution is not limited to writing reports. The page notes that in 2025, over 7,300 local, state, and federal transportation leaders met with business leaders and researchers — an example of the Academies acting as a convening body where practitioners and experts exchange information. Convening is a distinct form of contribution from authoring: it surfaces problems and builds shared understanding before formal recommendations exist.

What kinds of expertise are involved

The three-part name signals the breadth:

The page frames these as complementary: "Together, they can help us build a thriving and healthy society." In practice this means a single study may draw on physicists, engineers, clinicians, economists, and policy specialists at once — which is why committee composition is a central part of the process.

Current example: AI progress and safety

The Academies describe themselves as having been "at the forefront of efforts to better understand what these advances in AI mean for researchers and society at large," in the context of concerns about pursuing AI safely without stifling technological progress. This is a useful case for seeing the model in action: a fast-moving technical field where policymakers need a credible, non-advocacy synthesis of what is known. The contribution of experts here is to translate specialized knowledge into a form that can inform public discussion and policy.

How to engage with the output

If your goal is to use this work rather than join it:

• Start with reports and consensus studies on your specific topic — these are the substantive products of the committee process.
• Look for decadal surveys if you need to understand where a scientific field is heading and what funders are likely to prioritize.
• Check news releases and statements for current activity, such as the release of a new edition of a widely used guide to responsible research, or the presidents' statement of support for colleagues at the National Academy of Sciences of Ukraine.
• Note the date context on items you rely on; the page evidence includes announcements dated across September 2026.

What this means practically

The takeaway is that the National Academies function less like a think tank with resident scholars and more like a standing process for mobilizing outside expertise on demand. The scale — over 20,000 participants in 2025 — is what allows that process to cover everything from astronomy to transportation to research ethics. Whether you are a researcher wanting to contribute, a policymaker looking for an authoritative synthesis, or a member of the public trying to understand a technical debate, the entry point is the same: find the committee or report that addresses your question, and treat its consensus findings as the product of many experts rather than one voice.
