It's possible but it must be approved in advance via this form and will need to satisfy the requirements below:
At the end of the internship, you'll need to petition for final approval.
The petition will need to be accompanied by three reports on the internship: (1) one by you, (2) one from your supervisor at the organization, and (3) one from the faculty member overseeing the class and responsible for assigning the grade. Often, all three reports will be normal parts of your internship and can be forwarded with your petition. If your internship does not require you to submit a report we can provide a template.
If all of the reports are satisfactory, your petition will be approved and you'll be able to count the internship toward the Policy Studies 410 requirement.
Please note that only internships that are approved in advance will be accepted in lieu of 410. It is NOT possible to have an internship approved after the fact.
