Teaching Load Calculator

Faculty teaching load is the sum of the weekly hours an instructor devotes to instruction and its supporting duties. The contact-hour component is the visible part: courses multiplied by scheduled class hours, which is why a 3-3 load in three-credit courses yields 9 contact hours per week. The invisible part - preparation, grading, and office hours - typically exceeds it. This calculator adds those four components into a weekly total, then applies a weighted workload-unit conversion of 1.0 per contact hour, 0.5 per preparation hour, 0.75 per grading hour, and 0.5 per office hour, reflecting the common institutional practice of treating direct instruction as the most demanding activity per unit of time. Useful benchmarks: research universities assign 2-2 loads (about 12 credit hours per year), comprehensive universities 3-3 or 3-4, and community colleges commonly 5-5, or roughly 15 contact hours per week. Preparation runs 2 to 3 hours per contact hour for a new course and 1 to 1.5 hours for a repeated one. Grading estimates of 10 to 15 minutes per student per written assignment scale quickly: 120 students across four sections is 20 to 30 hours per grading cycle. The tool classifies totals above 50 hours per week as excessive. The main limitation is that committee service, advising, thesis supervision, curriculum development, and accreditation work are excluded, so a result near 40 hours often understates the real commitment.

Formal workload accounting in American higher education grew out of the credit-hour system. Charles W. Eliot at Harvard and later the Carnegie Foundation for the Advancement of Teaching promoted a standard unit of academic time in the first decade of the twentieth century; the Carnegie unit, defined around 1906 in connection with the foundation pension system, fixed the convention that one credit hour represents one hour of class contact plus roughly two hours of student work per week. Because the unit was designed to measure student effort, institutions later repurposed it as a proxy for faculty effort, which is the source of much of the ambiguity in workload policy today. The American Association of University Professors began publishing statements on faculty workload as teaching obligations expanded, arguing that a maximum of about 12 contact hours per week is compatible with active scholarship and that heavier loads should carry correspondingly reduced research expectations. Post-war growth in enrollment, the rise of the community college sector in the 1960s, and later state-level accountability reporting pushed institutions to adopt weighted workload-unit systems that could compare a laboratory section, a seminar, and a large lecture on a single scale. Since the 1990s, collective bargaining agreements and, more recently, online course delivery have prompted further revisions, with many institutions counting online sections at 1.25 to 1.5 times an in-person equivalent.
