Both the school and coach are required to send letters to the NCAA agreeing to abide by any restrictions imposed.
They must also report back to the NCAA every six months until either the end of the coach's employment or the show-cause penalty (whichever comes first).
[1] The penalty is intended to prevent a coach from escaping punishment for violations that he/she had a role in committing or allowing—which are generally applied to the school (e.g., lost scholarships, forfeited and vacated wins)--by merely resigning and taking a coaching job at another, unpenalized school.
Contrary to popular belief, an NCAA member school is allowed to hire a coach who is under an ongoing show-cause order.
Many coaches who receive a show-cause penalty never coach again even after the penalty expires, since a large number of athletic directors and university presidents/chancellors are unwilling to hire someone with a history of major violations due to the potentially disastrous effects the hiring could have on the program.
