Who is the Department Chair for AP Capstone at Xavier?

The correct answer is Mrs. Rebecca Richter. She holds the position of Department Chair for the AP Capstone program at Xavier, which indicates that she is responsible for overseeing the curriculum, faculty, and other aspects related to the Advanced Placement Capstone classes. This leadership role suggests a significant level of expertise in AP programs and the ability to guide students and teachers towards academic excellence in this particular area of study.

It's essential to note that the other individuals listed, while potentially having roles within the school or related departments, do not hold the specific title of Department Chair for AP Capstone. Thus, their connection to the program may be different—perhaps as teachers or in other administrative capacities, but they do not have the same responsibilities or oversight as Mrs. Richter.
