The time line for internships

Teaching Internships for Ph.D. students: It is suggested students sign up for the teaching internship the semester immediately following the passing of required qualifying exams. Students can sign up for only one teaching internship course per semester. Detailed policy and procedure are given in the Internship Handbook.

NonTeaching Industrial Internships: It is suggested that industrial internships are taken during summer time between the end of the spring semester and the beginning of the fall semester for approximately 12 weeks (or equivalent to 480 hours). It is possible that a student may take the industrial internship during the regular semester, especially for those students who are holding a fulltime or a parttime job. Detailed policy and procedure are given in the Internship Handbook.

For Ph.D. students: If a Ph.D. student is interested in a threehour industrial internship, s/he is suggested to make the plan immediately after passing the required qualifying exams.

For M.S. students: s/he is suggested to begin looking for an internship before the end of the first semester of the program (which will be most likely the end of the first fall semester), in order to secure an industrial internship for the coming summer. It is possible that a student take the industrial internship during the second summer after enrolling to the program.

For international students who are interested in an industrial internship: In addition to the required forms for domestic students, international students are required to apply for Curricular Practical Training(CPT) through the Office of International Affairs.
