"This is a great question! I would say that any coursework related to dispute resolution would be helpful. I have stellar administration skills and would like to learn even more when it comes to increasing my ability to put out fires before they escalate to the executive whom I support."

The interviewer would like to know that you have an interest in continued learning, and education. There are many admin related courses available whether they be online, at a community center, or at your local college or university. Chances are, the class that you would choose is one of your areas of weakness, so this question can be a less direct way of asking what your greatest weakness is. The way in which you reply could also give the interviewer an indication of your most significant interests when it comes to the scope of your administrative work.

"I believe that continued education is vital, so I do appreciate you asking this question. If I could take any admin related coursework, I would take a workshop on technical writing. In my current role, and in this role with your company, I see that a lot of the admin work is related to curriculum writing and preparing RFP's and RFQ's. I am confident in my existing skills; however, there is always room to improve."
