In point number two, the underrepresented sex is easy to determine.  Title IX came into effect because women’s rights were being violated, therefore, women must be the underrepresented sex.

Option number two becomes invalid for some schools due to the fact that the school might not have a history of expanding athletic opportunities, or they might have a history, however the school has done everything they can to create equality amongst men and women and now they can no further expand the opportunities for women.  So in essence, a school has fulfilled this requirement.  The phrase continuing practice of expanding athletic opportunities, in point number two, refers to schools having to continue to uphold equal rights among men and women.  If a school simply continues to give women equal opportunities, then they have completed this requirement. 

In point number three schools are becoming forced to offer sports that might not be as big for women, as they are for men.  There is a small minority of women that are interested in participating in such sports like ice hockey and lacrosse, but a larger majority of men that play them.  Many schools still offer these sports for women, but they don’t offer them for men.  It has been determined that women are the underrepresented sex, and yet now they have received every sport, and in some cases more sports, then male athletes.  More men might be interested in a certain sport, like ice hockey, then women, however, it is very easy for the men’s team to get cancelled instead of the women’s team, due, of course, to point number three.
