2) mutualistic/ collaborative

Time capacity,
Coverage,
Credibility,
Scale and context		 Funded;
Direct engagement with policymakers/ practitioners		 Government bodies, Industry, Third sector, NGOs Effective for both short- and long-term policy decisions
Professional Partnerships (effective) Co-creation: “policy/ practice- research collaborations, usually with a limited lifespan” (footnote 3) (footnote 4)  (i.e. expert elicitation, committees, networks, Areas of Research Interest, etc.) Scale and context,
Navigating politics,
Long-term impact		 Often funded;
Direct engagement with policymakers/ practitioners; Fosters mutual understanding		 Researchers and policymakers/practitioners Highly effective under specific conditions: 1) funded, 
2) long-term perspective, 
3) mutualistic/ collaborative in nature
Training and fellowships (undetermined) Co-creation: formal skills development scheme, often funded (i.e. skills training), secondments, internships, fellowships.  Engagement,
Unpredictable knowledge base, Clarity, Comprehension		 Direct engagement,
Capacity-building,
Potentially funded		 Researchers and policymakers/practitioners Unclear/mixed/unavailable evidence on effectiveness.
