How were the Challenge Topics chosen?
Topics were chosen through extensive discussion among members of the scientific leadership of NIH. Many of the topics reflect issues identified in the strategic plans developed by each NIH Institute and programmatic office, bearing in mind that ARRA funding would be available only for two years. NIH Institute and Center plans are generally developed with public input, including the National Advisory Councils of the NIH Institutes and Centers, and in some cases, the US Congress.
