To ensure success when managing Interns within your respective organizations be sure to adhere to the following which are inspired in large part by Do Interns Take Lunch Breaks Too? Five Mini Case Studies of the Intern Experience…and What Managers Can Learn from It, by Krista M. Reaves:

• Stick to your word with respect to working hours. 
• Be up front and honest with respect dress code expectations. Interns do not have money to waste on unnecessary clothing purchases (e.g. they buy professional attire only to learn that you are a casual environment).
• Ensure that the Intern is provided workspace with other relevant members of the team.
• Ensure that your Interns receive an orientation to your business and office locations. Simple things like where is the bathroom, the break room, etc. may not seem important but they are very important if you don’t know. Also, ensure that your Interns are introduced to other team members, particularly those they will be working with and/or contacting for assistance.
