Steering Committee Members
The steering committee oversees the report authors, reaches conclusions based on the findings of the authors and writes an executive summary.
Committee Selection and Approval
Selection of appropriate committee members, individually and collectively, is essential for the success of a study. All committee members serve as individual experts, not as representatives of organizations or interest groups. Each member is expected to contribute to the project on the basis of his or her own expertise and good judgment. A committee is not finally approved until a thorough balance and conflict-of-interest discussion is held, and any issues raised in that discussion are investigated and addressed. Members of a committee are anonymous until this process is completed.
Careful steps are taken to convene committees that meet the following criteria:
The committee must include experts with the specific expertise and experience needed to address the study's statement of task. A major strength of CCST is the ability to bring together recognized experts from diverse disciplines and backgrounds who might not otherwise collaborate. These diverse groups are encouraged to conceive new ways of thinking about a problem.
Having the right expertise is not sufficient for success. It is also essential to evaluate the overall composition of the committee in terms of different experiences and perspectives. The goal is to ensure that the relevant points of view are, in CCST's judgment, reasonably balanced so that the committee can carry out its charge objectively and credibly.
All provisional committee members are screened in writing and in a confidential group discussion about possible conflicts of interest. For this purpose, a "conflict of interest" means any financial or other interest which conflicts with the service of the individual because it could significantly impair the individual's objectivity or could create an unfair competitive advantage for any person or organization. The term "conflict of interest" means something more than individual bias. There must be an interest, ordinarily financial, that could be directly affected by the work of the committee. Except for those rare situations in which CCST determines that a conflict of interest is unavoidable and promptly and publicly discloses the conflict of interest, no individual can be appointed to serve (or continue to serve) on a committee used in the development of reports if the individual has a conflict of interest that is relevant to the functions to be performed.
Point of View
Point of View
A point of view or bias is not necessarily a conflict of interest. Committee members are expected to have points of view, and CCST attempts to balance these points of view in a way deemed appropriate for the task. Committee members are asked to consider respectfully the viewpoints of other members, to reflect their own views rather than be a representative of any organization, and to base their scientific findings and conclusions on the evidence. Each committee member has the right to issue a dissenting opinion to the report if he or she disagrees with the consensus of the other members.
Membership in CCST and previous involvement in CCST studies are taken into account in committee selection. The inclusion of women, minorities, and young professionals are additional considerations.
Specific steps in the committee selection and approval process are as follows:
Staff solicit an extensive number of suggestions for potential committee members from a wide range of sources, then recommend a slate of nominees. Nominees are reviewed and approved at several levels within CCST.
A provisional slate is then approved by CCST's Board. The provisional committee members complete background information and conflict-of-interest disclosure forms. The committee balance and conflict-of-interest discussion is held at the first committee meeting. Any conflicts of interest or issues of committee balance and expertise are investigated; changes to the committee are proposed and finalized.
CCST's Board formally approves the committee. Committee members continue to be screened for conflict of interest throughout the life of the committee.

Peer review is the process of the evaluation of the scientific and technical merit (and likelihood of success) of the proposed research project/program by a panel of reviewers with direct expertise in the area of research to be evaluated who have no personal stake or interest in the outcome of the evaluation process. The salient features of the peer review process are the evaluation of the research program by "peer" experts in relevant fields who are deemed qualified to evaluate the product based solely on the scientific and technical merit of the content. It is standard practice to keep the identity of peer reviewers confidential as well as all of the comments and deliberations.
All CCST reports are peer reviewed using guidelines and processes established by CCST to assure the highest scientific and technical standards. Guidelines are similar to those of the National Academy of Science, adapted to be appropriate for California. It is standard practice to keep the identity of peer reviewers confidential as well as all of the comments and deliberations.
