What is the ruling on taking money for teaching in an academic support program at the university, knowing that the nature of residency does not allow for work, and that the purpose of teaching is self-improvement?

A student's teaching within their own institution is not considered a violation of residency regulations if it is part of their studies for strengthening their skills, and what they receive is considered a reward for their cooperation. The institution may also have exceptions that allow it to benefit from the services of its students, with or without pay, and the matter is subject to the regulations and laws governing such activities.
