Supporting organisations that produce, teach, and use evidence syntheses worldwide.

Global partnership

A shared space for evidence synthesis organisations.

Evidence Synthesis International is a partnership of organisations from around the world. It supports collaboration between groups that develop methods, build capacity, share resources, advocate for evidence-informed decisions, and promote the practical use of syntheses.

The partnership reflects a broad evidence community, including human health, conservation, education, veterinary medicine, public policy, and other fields where research needs to be gathered and interpreted carefully.

About evidence synthesis

Bringing completed studies together clearly.

Evidence synthesis uses formal, explicit, and rigorous methods to bring together findings from completed studies. It helps people understand what is known, what remains uncertain, and how research can inform practical decisions.

Good synthesis is transparent, structured, and useful. It can support policy, practice, education, conservation action, health decisions, and wider public benefit.

Impact fields

Evidence synthesis is used across many disciplines.

The methods and principles of synthesis can support any field where existing research needs careful, transparent interpretation.

Human health

Informing questions about interventions, systems, services, and population-level outcomes.

Conservation

Supporting environmental decisions through careful review of ecological and conservation evidence.

Education

Helping educators and policymakers understand what research suggests about learning and equity.

Veterinary medicine

Strengthening evidence-informed animal health, welfare, and applied veterinary practice.

Public policy

Connecting research findings with policy questions, implementation contexts, and public needs.

Cross-sector learning

Sharing methods, tools, standards, and experience across evidence communities.
