The Northwest Commission on Colleges and Universities requires that each college credit entail 40-45 hours of student involvement (class time plus outside assignments). The following table shows how this determines the amount of student involvement for credit courses for the most commonly used number of units.

Units in a Course Student Involvement:

• 0.5: 20 – 22.5 hours
• 1.0: 40 – 45 hours
• 2.0: 80 – 90 hours
• 3.0: 120 – 135 hours
• 4.0: 160 – 180 hours
• 5.0: 200 – 225 hours
• 6.0: 240 – 270 hours
