About the series
An NSF Committee of Visitors (COV) is asked to provide “a balanced assessment of . . . performance in two primary areas, the integrity and efficiency of the processes related to proposal review, and the quality of the results of investments in the form of outputs that appear over time. The COV also explores the relationships between award decisions and program/NSF-wide goals in order to determine the likelihood that the portfolio will lead to the desired results in the future . . . . It is important to recognize that reports generated by COV’s are used in assessing agency progress in order to meet government-wide performance reporting requirements, and are made available to the public. . . .” (Committee of Visitors Reviews, NSF Manual 1, Section VII).
