Across the Washington area, International Baccalaureate is booming, with more than two dozen high schools offering the college-level program and more signing up all the time. College admissions officers say they love seeing IB courses on transcripts. Students say the IB writing instruction and five-hour, end-of-course exams prepare them well for higher education.
But there’s a catch: Students usually can’t get college credit for one-year IB courses, even though they are similar to one-year Advanced Placement courses, which are eligible for credit. In another complication, students can get credit for passing tests after two-year IB courses, but that credit is equivalent to one year in AP.
Most university officials say they can’t explain these discrepancies. In many local high schools, bewilderment and frustration are growing among students and teachers over college policies about IB that seem at odds with the colleges’ oft-stated support for more challenging high school curricula.
“Imagine the consternation of these students who are getting the very best scores possible and are not seeing any recognition at most colleges,” said Marilyn Leeb, IB coordinator at Washington-Lee High School in Arlington County.
“I feel like we were being cheated,” said Chad King, a 2007 graduate of Mount Vernon High School in Fairfax County who received no credit for one-year IB courses from Ohio Dominican University in Columbus. “IB puts a lot of stress and pressure on its students, and for us not to get credit just because it is not AP is unfair.”
