The GRADE began in the year 2000 as a collaboration of methodologists, guideline developers,
biostatisticians, clinicians,
public health scientists and other interested members. GRADE developed and implemented a common, transparent and sensible approach to grading the quality of evidence (also known as certainty in evidence or confidence in effect estimates) and strength of recommendations in healthcare. GRADE follows careful methods to develop its guidance and other articles.
GRADE official articles, guidance group, project groups and centers, networks, and formalization of Evidence-to-Decision frameworks As GRADE adoption expanded, the need for sustained methodological support and capacity building became apparent. Starting in
2010, the
first GRADE Centers and Networks were established. These entities supported training, implementation, and feedback from diverse contexts, helping to ensure consistent application while allowing for contextual adaptation. During the same period, the
DECIDE Project, funded by the European Commission, played a central role in formalizing
Evidence-to-Decision frameworks. DECIDE supported the development and testing of EtD frameworks for different types of decisions, the publication of EtD guidance articles, and the
implementation of EtD frameworks within GRADEpro.9 This work transformed EtD from an early concept into a standardized and operational component of GRADE.
Governance, methodological stewardship, and the development of GRADE guidance As GRADE matured and its applications expanded across clinical medicine, public health, diagnostics, and health systems by many influential organizations, the need for
formal methodological stewardship and governance became increasingly apparent. What had initially functioned as an informal working group required clearer structures to ensure coherence, transparency, and consistency in how new methodological developments were proposed, debated, approved, and disseminated.
The GRADE Guidance Group In response to this need, the
GRADE Guidance Group (often referred to as G3) was established in the early 2010s as the core governance body of the GRADE Working Group. The Guidance Group provides
strategic oversight and methodological stewardship for GRADE. Guided by its chair (currently: Holger
Schünemann) its responsibilities include: • setting priorities for methodological development, • reviewing and approving proposals for new guidance or major updates, • ensuring consistency across guidance documents, • safeguarding the conceptual integrity of GRADE, and • coordinating across the growing number of contributors, centers, and networks. The creation of the Guidance Group marked an important transition in GRADE’s evolution—from a predominantly informal collaboration to a
self-governing methodological enterprise. Importantly, the Guidance Group does not replace the broader GRADE Working Group; rather, it provides structure and continuity, while maintaining GRADE’s collaborative and consensus-driven ethos. Current members (as of 2025) include: Elie Akl, Sue Brennan, Philipp Dahm, Marina Davoli, Monica Hultcrantz, Miranda Langendam, Joerg Meerpohl, Reem Mustafa, Ignacio Neumann, Holger
Schünemann, Nicole Skoetz, Jun Xia.
GRADE Project Groups At that time, substantive methodological advances within GRADE began to be developed through
GRADE Project Groups. These groups are convened to address specific methodological questions or gaps, for example, how to apply GRADE to animal research, rare diseases, public health interventions, health systems decisions, or how to assess domains such as imprecision, publication bias, equity, or values. Project groups are typically multidisciplinary and international, bringing together methodologists, content experts, and end users. Their work commonly involves: • reviewing existing methods and frameworks, • conducting empirical or conceptual methodological work, • testing proposals in real guideline or decision-making contexts, • and iteratively refining approaches through discussion and application. Project groups operate under the oversight of the GRADE Guidance Group, which reviews proposals, monitors progress, and evaluates final outputs before endorsement. This structure has allowed GRADE to
scale methodologically without fragmenting into competing or incompatible approaches.
Formalization of GRADE guidance and concept articles As the volume and diversity of GRADE-related publications increased, the Working Group recognized the importance of clearly distinguishing
official GRADE guidance from conceptual discussions, applications, or commentaries. In response, a
formal article was published describing the processes by which GRADE Guidance and GRADE Concept articles are developed, reviewed, and approved. That article clarified, among other points: • the distinction between
GRADE Guidance articles, which provide authoritative, endorsed methodological instructions, and
GRADE Concept articles, which explore ideas, extensions, or emerging areas without yet constituting formal guidance; • the role of the GRADE Guidance Group in approving guidance proposals and final manuscripts; • expectations regarding transparency, documentation of methods, and consensus-building; and • the importance of linking guidance development to real-world testing and application. This formalization was a critical step in maintaining trust and clarity as GRADE became widely used. It helped readers, guideline developers, and organizations understand
which publications represent official GRADE methods, which are exploratory or developmental, and how new guidance evolves from concept to endorsed standard. ==GRADE components==
