On-campus credit courses for the professional development of community college faculty have proven to be a highly effective means of improving the quality of instruction at McLennan Community College (Waco, Texas). If carefully designed, implemented, and evaluated, these courses can provide an appropriate alternative to faculty enrollment in postgraduate courses at other institutions. A successful program of professional development courses must include a clear recognition of the faculty's instructional needs and interests; offer faculty members maximum convenience, economy, and time efficiency; and utilize appropriate evaluative procedures to determine the courses' instructional value for both the enrolled faculty members and their own students. (Extensive appendixes include explanations of professional development requirements and salary schedule credits, a sample course proposal and prospectus, the syllabus and evaluation of a faculty workshop, and a list of noncredit seminars and credit courses offered at the community college.)
