First All-girls High School in the State

In 1994 Trinity became the first women’s high school in Illinois to be accepted into the International Baccalaureate (IB) Organization. 

Modeled after the best educational systems in Europe, the IB program was originally designed in 1968 to meet the educational needs 
of children of diplomats.  Today, the IB program is offered to any student who wishes to challenge herself academically by pursuing an intensive course of study in six subject areas that leads to the reward of the IB diploma which may provide admission to top colleges and universities around the world.  Beyond intellectual rigor, the curriculum fosters responsibility, self-discipline, divergent thinking, internationalism and compassion.  It consistently attracts highly motivated and talented students who wish to excel as well-rounded individuals within a global society. Lauded by both educators and students alike, the IB is increasingly being recognized as the best college-preparatory curriculum an American school can offer.
