Middlebury Institute of International Studies at Monterey. Formerly the Monterey Institute of International Studies
My prior coursework at another school seems to be identical to one of the courses required for my degree. Can I be waived from taking this course and use those credits to take elective courses?

It may be possible to be waived from a degree requirement, the credits would then become additional elective credits for your degree program.  Complete the Petition for Waiver of Academic Regulations, attach your transcripts, a course description and syllabus.
