Both second and third year students may enroll in externships, and may enroll in more than one externship program under specific guidelines (see below).
You may take up to 16 units during your second and third years in Clinicals and Externships (Law 420 through 480) and the following courses:

Law 298 (Group Study);
Law 299 (Independent Research);
Law 408 (Community Education Seminar);
Law 410A & B, 414 (Moot Court);

Law 419 (Adv. Writing Req.); and

There is a maximum of 14 units in Externships.

An additional 4 units (for a maximum of 20 units) may be taken under specific guidelines and with the advance approval of the Assistant Dean of Student Affairs (Dean Kulwin).
Students may take 2-6 units per semester in all the externships, with the exception of Legislative Process, in which the maximum semester units are four (4), and Criminal Justice in which the minimum is three (3) units.  All externs must keep records of the time spent at their placements. For each unit of credit received in an externship program, the student shall work at the placement 4 hours per week for the 15 weeks of the semester.

Enrollment in an externship placement for more than one semester or after employment at the same placement:  Students may take externships in subsequent second and third semesters at the discretion of the faculty under the following circumstances: The experience from semester to semester is cumulative and varied, not repetitive, and differs substantially from the work previously undertaken; the nature of the work done could not have been compressed into one semester, or the student’s schedule would not permit such intensity. The maximum number of units at any one placement is 12.
Students may enroll in the Criminal Justice and Judicial externships on a full time basis (12 units per semester).Full-time Judicial externs must take Judicial Process Seminar 261, 2 units, either prior to or concurrently with the externship. The seminar is only offered in the fall semester. Generally, students should wait until their fourth or fifth semester to do a full time externship.  The student must be in good standing. Students will work 40 hours per week for 16 weeks.  Thus, if the externship begins on the first day of law school instruction, it will end one week after the last day of law school instruction.

Semester away students may take an additional 2 unit non-clinical/externship class for a total of 14 semester units.  With permission of Dean Kulwin, a student may take a 3 unit non-clinical class.  If a student elects to take an additional 3 units, he or she will receive only 11 credits for the externship but will still be required to complete 40 hours of work for 16 weeks.  Time devoted to course work is in addition to the externship 40 hours per week. The student will receive no more than a total of 14 semester units during any full time externship semester.  This limitation cannot be waived.
