"Most states have adopted a 150 university semester hour educational requirement. A few states require only a four year university degree." Depending on how your hours are calculated, I think 150 might require a year of grad school generally. My school does 3 hours of class per week x 5 classes per semester x 8 semesters = 120 hours.

On the other extreme, the CFA institute requires 4 years of experience to sit the CFA exams.
