You’re required to spend about 160 hours on CMM/ART 490 to earn three hours credit. You should work at least 10 hours a week during spring or fall semesters and at least 15 in the summer session. The guideline is 55 hours of internship effort per academic credit hour: 1=55, 2=110, 3=165, 4=220. Five- or six-hour internships are rare. You’d have to be working full time for most of the semester to do this.
