An evaluation was conducted at Florida Junior College (FJC) of the four-day operational week implemented during May through August, 1981. Surveys were administered in May and July to day students, full-time teaching faculty, and full-time noninstructional staff to determine their level of satisfaction or dissatisfaction with the four-day week. Responses to the first survey were obtained from 16.2% of the students, 60.4% of the teaching faculty, and 66.6% of the noninstructional staff; response rates on the second survey were 15.9% of the students, 49.6% of the faculty, and 60.4% of the noninstructional staff. In addition, administrators kept a log of incidents relating to the college being closed on Fridays and a frequency count of contacts initiated during the extended hours before 8:00 am and after 5:00 pm. The evaluation found that the four-day week had no overall effect on students' academic performance. Savings in electricity usage were realized, and there was no adverse impact on operational functioning. Students and the public used the services of the college during the additional two hours of operation. Approximately 75% of the students, faculty, librarians, and counselors recommended that FJC implement the four-day week during 1982 spring and summer terms, as did 70% of the career employees and a majority of the administrators. Extensive appendices include survey forms, respondent comments, and comparative grade distributions. (KL)
