“Credit hour” is the basic unit of collegiate-level instruction as determined by the Kansas Board of Regents in a subject or course offered at a level not higher than those subjects of courses usually offered to first- and second-year students in four-year institutions of post-secondary education. One credit hour is at least one hour of classroom or direct instruction plus two hours of out-of-class student work each week for a semester (or its equivalent). Utilizing the Carnegie Unit, “one hour” of instruction or class work equals 50 minutes. Credit hours do not include instruction in a subject or course taken by a student enrolled for audit or any subject of course not approved by the Kansas Board of Regents. The Kansas Board of Regents shall determine whether the subject and courses offered in the community colleges are at the level of first-year courses or sophomore courses offered in the state educational institutions and shall not approve a subject or course offered at a higher level. An equivalent amount of student work (minimum three hours per week for a semester of combined direct instruction and out-of-class student work) must be represented for a credit hour in other academic activities such as laboratories, internships, practical labs, studio work, and other academic work.
