A college dean oversees important issues in what may be a huge institution with thousands of students, so don't waste her time. Take an hour or two before the meeting to list key points and brainstorm answers to potential questions. Know your stuff.
For example, if you're a budget committee head and the dean has asked you for a meeting on the year's budget process, look over your committee meeting notes, call fellow members for insights and prepare evidence of your progress. If you are a potential student meeting with the dean of admissions, research common interview questions and rehearse your answers. If you show up prepared, the meeting will go more smoothly and the dean may look more favorably upon you.
Although the dean may wield considerable influence, he isn't necessarily someone to fear. If you have done your homework and are ready for the meeting, relax. Be yourself and put your best foot forward. Don't be afraid to inject a little humor (if appropriate) into your conversation. Greet the dean with a firm handshake and a smile. Keep things appropriately formal but friendly. Project an air of confidence in your answers to his questions. If he asks a question that stumps you, don't panic. Stay calm and say something like, "That's a very good question. I'd like to think more about it and get back to you, if that's OK."
It's important to present a capable, confident front, even if you're nervous. No matter how well your answers come out, your body language may betray your anxiety. Don't cross your arms or stuff your hands in your pockets. Don't play with your hair or touch your face unnecessarily. Don't slouch. Sit up straight and maintain eye contact. Don't lean on your elbow, tap your foot or bounce your knee -- these can make you seem restless and eager to get away. Sit still and focus on the conversation.
Unless you requested the meeting, let the dean take the lead and set the pace and tone of the meeting. Answer her questions thoroughly and concisely. Avoid including unnecessary information, such as an anecdote, unless it is relevant and specifically illustrative of your point. In an admissions interview with a dean, don't ask questions until she tells you it is appropriate to do so. In a business meeting, finish supplying the dean with all the information she has requested before asking your own questions.
The end of the meeting is the time to drive home your message. Take the opportunity to summarize your points, desire to attend the dean's college or why you deserve the promotion in question. Leave the dean with a strong positive impression of you. If you're interviewing for admission or a job, ask when you can expect to receive an answer. If you're concluding a business meeting, invite the dean to contact you with further questions. Always sincerely thank the dean for his time, offer a smile and a handshake and promptly show yourself out.
