Review Process

Developing a Team, Work Plan, and Protocol

Each review team consists of a Principal Investigator (PI), a Deputy PI, a Project Coordinator (PC), and reviewers. The PI for each topic is a well-known expert in his or her field and is responsible for leadership in conceptualizing the specific topic area, identifying and addressing issues during the review, and developing and reviewing topic and intervention reports.

The Deputy PI is an established researcher with relevant methodological and substantive expertise. The Deputy PI oversees the work of the WWC Review Team, reviews research ratings, develops the review protocol, and writes reports in collaboration with the PI.

Reviewers have experience conducting critical reviews of research and have training in research design and methodology that is relevant to reviewing evidence of effectiveness. As part of the review team, reviewers review and summarize the evidence of effectiveness as well as drafting intervention reports. Each reviewer goes through an extensive training and certification process before working on WWC reviews.
