Are you taking the Capstone (ENS 550) in Fall 2014? Keep in mind that you cannot wait until the last minute to think about it. You need to send a draft of your internship plan to Dr. Megan Styles by April 15. Also, if your internship is unpaid, you need to work with Dr. Dennis Ruez to complete an affiliation agreement. That is a legal document that has sometimes taken months to get approved. You will not be allowed to enroll in ENS 550 without a fully approved internship plan and affiliation agreement (if applicable).
Guidelines for the internship plan can be found in the graduate student handbook on the department home page.
