An educational curriculum that originally catered to the children of globe-trotting diplomats is making rapid inroads in K-12 public schools across the U.S., boosting test results and academic readiness even at inner-city schools.
An educational curriculum designed for the children of globetrotting diplomats is making rapid inroads in K-12 schools across the U.S., showing surprising improvements in test results and academic readiness even at inner-city schools. Caroline Porter has details.
Houston, Chicago, Tampa, Fla., and other cities are embracing the International Baccalaureate [SIS IB Link] program as a way to overhaul low-performing schools, attract middle-income families who might otherwise favor private schools, or offer more choice.
“It’s not a program for the elite,” said Samuel Sarabia, who runs the IB program for Houston Independent School District, where 10 schools have IB programs, including two where the majority of students qualify for free or reduced-price lunch. Five more low-income schools are in the midst of an IB conversion process run by the nonprofit International Baccalaureate group.
The program began in Geneva in the 1960s as a two-year high-school diploma offering for the children of diplomats and itinerant business executives. It later expanded into elementary- and middle-school programs.
Today, there are 1,651 IB programs in the U.S.–including 1,493 public schools–up from 503 in 2003. About 90% of them are in public schools, and most are aimed at U.S. students, not the children of diplomats.
Officials tout the programs’ emphasis on critical thinking. Unlike the traditional model of teachers imparting knowledge in a lecture format, IB programs emphasize individual and group projects governed by a philosophy of “international mindedness.” Students are required to take a second language.

The Madison School Board rejected the proposed Madison Preparatory IB Charter school in 2012, largely sponsored by the local Urban League.
