The American College of Sofia is an authorized IB World School and has offered the IB Diploma Programme since 2005. Students not earning a Bulgarian National Diploma are eligible for admission into the two-year IB program. ACS provides a challenging, college-preparatory curriculum for all IB students and hires teachers who are experts in their subject matter. Students who enroll in the IB Diploma Programme are also given the opportunity to fulfill the requirements for the ACS American diploma, which is awarded to students independently of the diploma granted by the International Baccalaureate Organization (IBO).

ACS offers a wide range of courses in the IB, including English A: Literature High Level (HL), French B: Standard Level (SL)/High Level (HL), Spanish B: SL/HL, German B: SL/HL, French Ab initio SL, Spanish Ab initio SL, German Ab initio SL, Economics HL, History HL, Biology SL/HL, Mathematics SL/HL, Mathematical Studies SL. In addition, Theory of Knowledge (TOK), Community-Action-Service (CAS), and the Extended Essay (EE) serve as integral components of the diploma, encouraging students to extend themselves intellectually, while also considering areas of social responsibility. The IB programme culminates in May of Year 2 when students sit for their final examinations.
