1. Understand the Purpose and Format of Your Defense

Before preparation begins, it’s essential to understand what a thesis defense entails:

• A thesis defense is an oral examination of your research by a committee of experts.

• Its purpose is to evaluate the originality, rigor, and significance of your work, as well as your ability to discuss and defend your findings.

• Formats may vary:

  1. Public defense: Open to faculty, students, or the public; common for Ph.D. candidates.

  2. Closed defense: Limited to the student and committee members; typical for master’s theses.

  3. Virtual defense: Conducted online via Zoom, Teams, or other platforms.

• Knowing the expected format, time limits, and audience is crucial for tailoring your preparation.
