Executive Order 14303 of May 23, 2025

Restoring Gold Standard Science
By the authority vested in me as President by the Constitution and the
laws of the United States of America, including section 7301 of title 5,
United States Code, it is hereby ordered:
Section 1. Policy and Purpose. Over the last 5 years, confidence that scientists
act in the best interests of the public has fallen significantly. A majority
of researchers in science, technology, engineering, and mathematics believe
science is facing a reproducibility crisis. The falsification of data by leading
researchers has led to high-profile retractions of federally funded research.
Unfortunately, the Federal Government has contributed to this loss of trust.
In several notable cases, executive departments and agencies (agencies) have
used or promoted scientific information in a highly misleading manner.
For example, under the prior Administration, the Centers for Disease Control
and Prevention issued COVID–19 guidance on reopening schools that incorporated edits by the American Federation of Teachers and was understood
to discourage in-person learning. This guidance’s restrictive and burdensome
reopening conditions led many schools to remain at least partially closed,
resulting in substantial negative effects on educational outcomes—even
though the best available scientific evidence showed that children were
unlikely to transmit or suffer serious illness or death from the virus, and
that opening schools with reasonable mitigation measures would have only
minor effects on transmission.
The National Marine Fisheries Service justified a biological opinion by adopting an admitted ‘‘worst-case scenario’’ projection of the North Atlantic right
whale population that it believed was ‘‘very likely’’ wrong. The agency’s
proposed actions could have destroyed the historic Maine lobster fishery.
The D.C. Circuit Court of Appeals subsequently overturned that opinion
because the agency’s decision to seek out the worst-case scenario skewed
its approach to the evidence.

Similarly, agencies have used Representative Concentration Pathway (RCP)
scenario 8.5 to assess the potential effects of climate change in a ‘‘higher’’
warming scenario. RCP 8.5 is a worst-case scenario based on highly unlikely
assumptions like end-of-century coal use exceeding estimates of recoverable
coal reserves. Scientists have warned that presenting RCP 8.5 as a likely
outcome is misleading.
Actions taken by the prior Administration further politicized science, for
example, by encouraging agencies to incorporate diversity, equity, and inclusion considerations into all aspects of science planning, execution, and
communication. Scientific integrity in the production and use of science
by the Federal Government is critical to maintaining the trust of the American
people and ensuring confidence in government decisions informed by
science.
My Administration is committed to restoring a gold standard for science
to ensure that federally funded research is transparent, rigorous, and
impactful, and that Federal decisions are informed by the most credible,
reliable, and impartial scientific evidence available. We must restore the
American people’s faith in the scientific enterprise and institutions that
create and apply scientific knowledge in service of the public good. Reproducibility, rigor, and unbiased peer review must be maintained. This order
restores the scientific integrity policies of my first Administration and ensures

that agencies practice data transparency, acknowledge relevant scientific
uncertainties, are transparent about the assumptions and likelihood of scenarios used, approach scientific findings objectively, and communicate scientific data accurately. Agency use of Gold Standard Science, as set forth
in this order, will spur innovation, translate discovery to success, and ensure
continued American strength and global leadership in technology.
Sec. 2. Definitions. For the purposes of this order:
(a) ‘‘Employee’’ has the meaning given that term in 5 U.S.C. 2105.
(b) ‘‘Scientific information’’ means factual inputs, data, models, analyses,
technical information, or scientific assessments related to such disciplines
as the behavioral and social sciences, public health and medical sciences,
life and earth sciences, engineering, physical sciences, or probability and
statistics. This includes any communication or representation of knowledge
such as facts or data, in any medium or form, including textual, numerical,
graphic, cartographic, narrative, or audiovisual forms.
(c) ‘‘Scientific misconduct’’ means fabrication, falsification, or plagiarism
in proposing, performing, reviewing, or reporting the results of scientific
research, but does not include honest error or differences of opinion. For
the purposes of this definition:
(i) ‘‘fabrication’’ is making up data or results and recording or reporting
them;
(ii) ‘‘falsification’’ is manipulating research materials, equipment, or processes, or changing or omitting data or results such that the research is
not accurately represented in the research record; and
(iii) ‘‘plagiarism’’ is the appropriation of another person’s ideas, processes,
results, or words without giving appropriate credit.
(d) ‘‘Senior appointee’’ means an individual appointed by the President
(or an individual performing the functions and duties of an individual
appointed by the President) or a non-career member of the Senior Executive
Service.
(e) ‘‘Weight of scientific evidence’’ means an approach to scientific evaluation in which each piece of relevant information is considered based on
its quality and relevance, and then transparently integrated with other relevant information to inform the scientific evaluation prior to making a
judgment about the scientific evaluation. Quality and relevance determinations, at a minimum, should include consideration of study design, fitness
for purpose, replicability, peer review, and transparency and reliability of
data.
Sec. 3. Restoring Gold Standard Science. (a) Within 30 days of the date
of this order, the Director of the Office of Science and Technology Policy
(OSTP Director) shall, in consultation with the heads of relevant agencies,
issue guidance for agencies on implementation of ‘‘Gold Standard Science’’
in the conduct and management of their respective scientific activities. For
the purposes of this order, Gold Standard Science means science conducted
in a manner that is:
(i) reproducible;
(ii) transparent;
(iii) communicative of error and uncertainty;

(iv) collaborative and interdisciplinary;
(v) skeptical of its findings and assumptions;
(vi) structured for falsifiability of hypotheses;
(vii) subject to unbiased peer review;
(viii) accepting of negative results as positive outcomes; and
(ix) without conflicts of interest.
(b) Upon publication of the guidance prescribed in subsection (a), each
agency head, as necessary and appropriate and in consultation with the

Director of the Office of Management and Budget (OMB Director) and the
OSTP Director, shall promptly update applicable agency policies governing
the production and use of scientific information, including scientific integrity
policies, to implement the OSTP Director’s guidance on Gold Standard
Science and ensure that agency scientific activities are conducted in accordance with this order.
(c) Each agency head shall, to the extent practicable, incorporate the
OSTP Director’s guidance on Gold Standard Science and the requirements
of this order into the processes by which their agency conducts, manages,
interprets, communicates, and uses scientific or technological information
prior to the finalization of the updated policies under this section.
(d) Within 60 days of the publication of the guidance prescribed in section
3(a), agency heads shall report to the OSTP Director on the actions taken
to implement Gold Standard Science at their agency.
Sec. 4. Improving the Use, Interpretation, and Communication of Scientific
Data. No later than 30 days after the date of this order, agency heads
and employees shall adhere to the following rules governing the use, interpretation, and communication of scientific data, unless otherwise provided
by law:
(a) Employees shall not engage in scientific misconduct nor knowingly
rely on information resulting from scientific misconduct.
(b) Except as prohibited by law, and consistent with relevant policies
that protect national security or sensitive personal or confidential business
information, agency heads shall in a timely manner and, to the extent
practicable and within the agency’s authority:
(i) subject to paragraph (ii), make publicly available the following information within the agency’s possession:
(A) the data, analyses, and conclusions associated with scientific and
technological information produced or used by the agency that the agency
reasonably assesses will have a clear and substantial effect on important
public policies or important private sector decisions (influential scientific
information), including data cited in peer-reviewed literature; and
(B) the models and analyses (including, as applicable, the source code
for such models) the agency used to generate such influential scientific
information. Employees may not invoke exemption 5 to the Freedom
of Information Act (5 U.S.C. 552(b)(5)) to prevent disclosure of such models
unless authorized in writing to do so by the agency head following prior
notice to the OSTP Director.
(ii) risk models used to guide agency enforcement actions or select enforcement targets are not information that must be disclosed under this subsection.
(c) When using scientific information in agency decision-making, employees shall transparently acknowledge and document uncertainties, including
how uncertainty propagates throughout any models used in the analysis.
