several policy-oriented issues have substantial S&T components that require input and advice from the S&T community. Table 1 provides examples of the many types of federal advisory committees, including the following:

Scientists, engineers, and health professionals recognize the need to serve pro bono on federal advisory committees that help to shape S&T policy. Such service provides the best scientific and technical information to policy makers and serves the S&T enterprise itself. Also, for all of the challenges that this approach presents, this uniquely American emphasis on voluntary, public input has served our nation well. The use of advisory committees by the federal government is a critical aspect of participatory government. The depth and breadth of knowledge and expertise that these bodies provide to policy makers expand intellectual resources well beyond those that can reasonably be provided by federal employees, particularly in rapidly evolving S&T fields.
