There is definitely a difference between having an intern, where they just do busy tasks; and having an intern that is brought in and is a part of the team-respected/taught/modeled for/etc. The intern host has a responsibility to the intern to provide them with a rewarding experience, one in which the student has takeaways and is allowed to grow. The intern has a responsibility to the site and host to be professional, prompt, and part of the team as well. This partnership needs to be explicitly laid out from the beginning, in order for all parties to benefit from an internship program.
