336: Expert Witness Theory and Practice

Credit Hours




The expert witness is a powerful weapon in a trial attorney's arsenal. Expert Witness Theory & Practice gives students the opportunity to learn about expert witnesses and work with experts in a mock trial environment. During this two credit hour course, students will learn who can be an expert, what an expert can testify about, the pretrial disclosure requirements for experts, differences between Illinois and federal law regarding experts, and the fundamentals of direct and cross-examination of experts. Students will then participate in simulations including a discovery deposition and a mock trial where students will present and cross-examine psychology graduate students serving as expert witnesses. Students will be graded on their performance of these exercises as well as written exercises and classroom participation. The mock trial will serve as the final examination for the course. Completion of Trial Practice or Evidence is highly recommended.
