Formula
Total Weekly Hours = Contact Hours + Prep Hours + Grading Hours + Office Hours
Contact Hours = Courses x Hours per Course. Prep Hours = Courses x Prep per Course. Workload Units assign weighted values to different activities: 1.0 per contact hour, 0.5 per prep hour, 0.75 per grading hour, and 0.5 per office hour. Total students equals courses multiplied by average students per course.
Worked Examples
Example 1: Research University Professor
Problem:A professor teaches 2 courses per semester, each 3 hours/week with 35 students. Prep time is 2 hours per course, grading takes 6 hours/week, and office hours are 4 hours/week.
Solution:Contact Hours = 2 x 3 = 6 hrs/week\nPrep Hours = 2 x 2 = 4 hrs/week\nTotal Weekly = 6 + 4 + 6 + 4 = 20 hrs/week\nTotal Students = 2 x 35 = 70\nGrading per Student = (6 x 60) / 70 = 5.1 min/student/week\nResearch Hours Available = 50 - 20 = 30 hrs/week\nSemester Total = 20 x 16 = 320 hours
Result:20 hrs/week (Light) | 70 students | 30 hrs available for research | 5.1 min grading/student
Example 2: Community College Instructor
Problem:An instructor teaches 5 courses per semester, each 3 hours/week with 28 students. Prep is 1.5 hours per course, grading takes 15 hours/week, and office hours are 5 hours/week.
Solution:Contact Hours = 5 x 3 = 15 hrs/week\nPrep Hours = 5 x 1.5 = 7.5 hrs/week\nTotal Weekly = 15 + 7.5 + 15 + 5 = 42.5 hrs/week\nTotal Students = 5 x 28 = 140\nGrading per Student = (15 x 60) / 140 = 6.4 min/student/week\nResearch Hours Available = 50 - 42.5 = 7.5 hrs/week\nSemester Total = 42.5 x 16 = 680 hours
Result:42.5 hrs/week (Heavy) | 140 students | 7.5 hrs for other work | 6.4 min grading/student
Frequently Asked Questions
What is a standard teaching load for college professors?
Teaching loads vary significantly by institution type. Research universities typically assign 2-2 loads (two courses per semester, both fall and spring), totaling 12 credit hours per year, allowing substantial time for research. Comprehensive universities often assign 3-3 or 3-4 loads, totaling 18 to 21 credit hours per year. Community colleges typically assign 5-5 loads, totaling 30 credit hours per year with minimal research expectations. Teaching-focused liberal arts colleges usually fall between 3-3 and 4-4 loads. These numbers represent contact hours only and do not include preparation, grading, office hours, and committee work that can double or triple the actual time commitment.
How much preparation time is needed per hour of teaching?
The general guideline is that each hour of classroom instruction requires 2 to 3 hours of preparation for a course being taught for the first time, decreasing to 1 to 1.5 hours for courses taught multiple times. This preparation includes reviewing and updating content, creating slides and materials, designing assessments, and planning in-class activities. Laboratory courses require additional setup time of 1 to 2 hours per lab session. Courses with rapidly changing content, such as technology or current events courses, require more ongoing preparation even after multiple iterations. New faculty members often underestimate preparation time, which contributes to excessive workloads in the first few years of teaching.
How does teaching load affect research productivity?
Research consistently shows a strong inverse relationship between teaching load and research output. Faculty with 4-4 loads publish approximately 60 percent fewer peer-reviewed articles than those with 2-2 loads. Each additional course per semester reduces annual publication output by roughly 0.5 to 1.0 articles according to studies of faculty productivity. However, the relationship is not purely linear because some teaching can inform and enhance research. Course releases, where faculty teach fewer courses in exchange for specific research commitments, are a common mechanism for supporting scholarly productivity. Sabbaticals and summer months provide concentrated research time that partially compensates for heavy teaching semesters.
How do office hours contribute to overall teaching load?
Office hours are a required component of teaching that is often undervalued in workload calculations. Most institutions require 3 to 6 office hours per week, but the actual demand varies significantly based on enrollment, course difficulty, and assessment schedules. During midterm and final exam periods, office hour demand can increase three to five fold. Virtual office hours through video conferencing have expanded accessibility but also increased the expectation of availability. Research shows that students who regularly attend office hours perform 10 to 15 percent better in courses, making this time valuable for student success. Effective office hours require preparation and energy comparable to classroom teaching.
