This was not the first competition for these schools. Most had participated in play days and games for quite a few years. Prior to league competition, emphasis was placed on the social aspect of sport. The refreshments and social hour after the game were as important or more important than the game. Rivalries were friendly and the game scores incidental.
In the first years schools were represented at league meetings by interested teachers and often students were delegated to attend. At first, some educators resisted the formation of a structured league. As new people entered the schools and assumed responsibility for sports programs changes occurred in the league.
Structure was added to the league, rules and policies were made to meet the needs of the emerging girl athlete. Regular meetings were held and slowly the emphasis shifted from cookies and punch to skill development and highly contested games. League championships were held and many regular season games were well attended.
With the onset of State sponsored tournaments for girls in 1975-76 it became obvious that the league was one of the strongest in the city and state. In the first state volleyball tournament Seton was AAA Runner Up and Ursuline AA Champions. Since then the league has usually been represented in State Tournaments in most sports.
The publicity and excellent play the League has fostered has meant opportunities for member students to receive athletic scholarships. College coaches look to this League for skilled athletics and Christian sportswomen to complement their programs.
As years go by additional sports have become League sports. All-League athletes are honored each year in all League sports. Each year the League takes on new challenges to improve girls' sports.
