For an alliance whose innovative methods are often held up as models for others to imitate, it is essential that Gavi evaluates "lessons learned". It does this through commissioned studies that are guided by its evaluation policy
The Vaccine Alliance evaluation policy guides how Gavi accesses its activities from 2008 onwards (Gavi Phase Two). The policy has been developed by the Gavi Secretariat and the Monitoring and Evaluation Technical Advisory Group (METAG) and has been reviewed by the Gavi Working Group.
As well as defining the objectives of Gavi evaluations in the context of the Vaccine Alliance's overall mission, the policy also identifies which Gavi activities will be assessed; this list includes projects, programmes and policies.
Criteria for each evaluation include relevance, efficiency, effectiveness, impact - negative or positive - and sustainability.
The policy also helps the alliance consider when evaluations should be carried out and by whom: during a policy's implementation or afterwards; by internal staff or outsourced; in a participatory manner or jointly among partners.
The policy also enables partners to carry out their own evaluations, emphasizing the importance of knowledge-sharing across the Vaccine Alliance. It also outlines how external evaluators should be selected and gives guidance on conflict of interest and transparency issues.
All Gavi evaluations are carried out according to international standards, guaranteeing independence, impartiality and transparency.
