A study was done of faculty perceptions of the accuracy and validity of various time-related personnel activity and productivity reporting measures, and of faculty's willingness to participate in these measures. In the first stage of the study 1,000 randomly-selected faculty from 200 institutions of higher education that have the highest levels of total separately budgeted science/engineering research and development expenditures were mailed a survey instrument entitled "Faculty Perceptions of Activity and Productivity Reporting." Faculty responses included suggestions for activity and productivity measures and those suggestions appeared in a followup survey, "Faculty Perceptions of Measures of Productivity," sent to the original cohort and an additional 10,000 science and engineering research and development faculty. The first survey received a 24 percent response rate; the second a 21 percent response rate. Results indicated that faculty think that reporting the percentage of time spent in various activities or the number of hours in the classroom is not a valid measure of their productivity. However, reliance on time-based reporting systems must prevail until institutions of higher education and faculty become accountable to their sponsors and begin to develop, implement, and make external and internal reports based on measures of faculty productivity.
