I think that the trouble comes from overloading terms. "student" already has a meaning. What distinguishes the special meaning from the more literal meaning? If I do not know that a special meaning is in use in a specific context, I can make a lot of mistakes.
I coin terms for our in-house client billing system. Two examples are "Work Function Code" and "Work Classification Code". These terms have precise meanings. It is possible for someone to misinterpret these, but I think that they are sufficiently unusual usage that most would ask what they mean instead of assuming as with "student".
One area of confusion we have is because of overloading. We use "client" to mean someone who buys from us (mainly services, for example order fulfillment) and "customer" to refer to someone who buys from one of our clients. Some of our employees do not make the proper (for us) distinction.
