Final answer:
The claim that Division III is the largest and most diverse division of the NCAA in terms of membership and conferences is true, with a varied profile of institutions.
Step-by-step explanation:
The statement that Division III is the NCAA's largest and most diverse division in terms of total institutional membership and the number of conferences is true. Unlike Division I and II, Division III is known for its larger number of member institutions, which have a wide range of profiles, from large public universities to small private colleges. This diversity includes differences in size, academic programs, and athletic resources. As for academic success, according to data collected by the NCAA, specifically mentioning the work of Hosick, the academic success of Division I college athletes between 2015 and 2019 was consistently high, although this fact is separate from the Division III claim and does not directly correlate with the membership size or diversity of Division III.
