IB is recognized as an excellent preparation for college-level work, and IB applicants are generally viewed as incredibly well-prepared.  

The IB recently published a research study examining Postsecondary outcomes of IB Diploma Program graduates in the US. Graduates of an IB program have higher four-year graduation rates than the US national average by more than 20%!

Hearing from university staff is even better:

“One of the advantages of an IB curriculum is its structure and quality. It is a coordinated programme, well established, well known and well respected. We know the quality of IB courses, and we think the IB curriculum is terrific.” - Christoph Guttentag, director of undergraduate admission, Duke University

“IB is well known to us for excellent preparations. Success in an IB programme correlates well with success at Harvard. We are always pleased to see the credentials of the IB Diploma Programme on the transcript.” - Marilyn McGrath Lewis, director of undergraduate admission, Harvard University

It is the 'best' high school prep curriculum an American school can offer.” - Marilee Jones, director of undergraduate admission, Massachusetts Institute of Technology 

"When prestigious colleges and universities evaluate applicants for admission, they seek students with the potential to succeed. Here are three things they believe an IB diploma will show about you - and that will help your college application stand out: 1) You have taken responsibility for your own learning, 2) You are prepared to conduct undergraduate research, and 3) You have expanded your learning beyond academic study." - The College of Wooster
