"Even as we celebrate the 40th anniversary of the passage of Title IX, we must still remain vigilant in our efforts to ensure equal opportunity for girls in education," said Russlynn Ali, assistant secretary for the Office for Civil Rights, in a statement. "The agreements reached in these four cases are representative of the important Title IX work that OCR continues to do, and should provide assurance to the thousands of girls in these school districts and across the nation that fundamental fairness on the playing field and in all areas of education is within their reach. OCR will continue to vigorously work to ensure equal opportunity."

The NWLC, using data submitted by the four school districts to the Education Department, determined there was an 11 to 14 percentage point gap between how many girls were enrolled and the share of athletic opportunities available to them. As part of the agreements, the four districts will conduct assessments to determine how to correct the inequities, including surveying students to identify areas of athletic interest that are not being met, and adding opportunities accordingly.

The announcement of the agreements comes at an interesting time. The London Olympics start later this month, and for the first time the United States' delegation will likely have more females than males. In an interesting twist, the June 23 anniversary date of Title IX is also known as "Olympic Day," marking the start of the modern Olympic Games.

As of Monday, it was expected there would be 10 more women than men among the athletes, although the qualifying events are not yet complete, said Patrick Sandusky, chief communications officer for the U.S. Olympic Committee. Also for the first time, the United States will have women competing in every sport at the Summer Games.

The increase in female athletes is the result of a combination of factors, including new sports for women being added, such as boxing, as well as more events being added to existing competitions including cycling, Sandusky said. Additionally, some women's teams, such as field hockey, qualified for the London Games. At the same time, some of the men's teams that had qualified in the past, such as soccer, fell short this time around.

Adding more spots on the teams is only part of the equation. Girls and women also have to be encouraged and supported in their efforts to reach for those athletic goals. While the playing field isn't yet level, the increase in participation and interest in girls' and women's sports nationally is a direct result of the impact of Title IX.

Regardless of their gender, the overwhelming majority of students will obviously never reach elite athlete status. But that doesn't negate the benefits - academic, social and societal - of playing sports. And it also doesn't undercut the reality that for millions of children, public school athletics programs are often their only opportunity to participate in organized sports of any kind.

"The many benefits of girls' participation in sports go beyond even the playing field and lead to higher academic achievement and graduation rates, lower teenage pregnancy rates, and overall better health," said Marcia D. Greenberger, the NWLC's co-president said in a statement Monday. "Our findings and OCR's investigation underscore the urgency to treating girls fairly and putting these schools on the path toward compliance with Title IX."
