The CCB internship program will approve quality internships regardless of whether they are paid or unpaid, Personally, I encourage companies to pay our interns as I believe most of our interns bring value to an organization. Many nonprofit organizations will not pay interns. Profit companies should be paying and about 60-70% of our internships are paid ones. Here's an interesting article about paid versus unpaid from a recent issue of USA Today. It discusses how some unpaid interns have brought lawsuits against internship providers and some have won.
