I graduated with an IB diploma in the 1990s. At my school, it was a program that you applied to before starting HS and you had to go through the entire four years. There were a few differences between participating in the IB program and taking AP classes (which I also took).
1. IB was a complete program ensuring that the students were "well-rounded"-- sort of like a liberal arts education. You could pick and choose the AP courses that suited your strengths (ex. AP Calc if you were good at math), but IB students were required to complete AP/IB Calc, chemistry, biology, English, history, and Spanish. IB students must also complete additional requirements to be eligible for the diploma including a "Theory of Knowledge" (philosophy) course, various projects, an "Extended Essay", and CAS (Creativity, Action, and Service) hours.
2. It was more writing intensive. This was the greatest benefit for me for college. I attended a prestigious private university, but still had many classmates with poor writing skills. Writing a 25 page paper during college was not a scary concept for me after all the writing and projects I had been required to do in HS.
3. There was a sense of community. While having your core classes consist of the same group of students for four years was a bit isolating at times, there were some benefits. Class discussions and presentations were more comfortable (building greater confidence) and we all knew each other well enough to collaborate outside of class. We also had more people than just a small group of friends to bounce ideas off and with whom to share our college admissions experiences and advice. (My DD, now in college, did not have these experiences and connections while taking AP classes in HS.)
