The responsibility not part of a sport parent's role according to the ASEP code of ethics is ensuring the child wins at all costs. Parents should encourage effort and sportsmanship over winning.
Step-by-step explanation:
According to the code of ethics developed by the American Sport Education Program, the responsibility that is NOT part of a sport parent's role is c) Ensure that the child wins at all costs. This is contrary to the principles of sportsmanship and ethical conduct that the code of ethics aims to promote.
