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.


ACS promotes the personal and intellectual development of each student through the IB programme, as outlined by the IBO.

- inquirers

Since December 2018, the American College of Sofia has begun working on the more than a year-long process of evaluation of the implementation of International Baccalaureate Diploma Programme (IBDP). Programme evaluation is both a requirement and a service provided by the IB Organization every five years and aims for the IB to ensure that the standards and practices of the programme are being maintained. However, equal in its importance, it is a process of formal and comprehensive self-evaluation involving all stakeholders within the ACS IB community, which is the source of new dynamism and momentum and provides an opportunity to reflect on achievements and new initiatives and increase communication within the school.

The College is expected to determine its own assessment of the implementation of the IB programme, according to the Programme standards and practices and programme requirements as well as to identify major achievements during the five-year period under review, 2015-2020,  and to identify practices that need further development.

As a major step in the process, the College is going to gather information for a comprehensive self-study among ACS stakeholders. It is going to survey IB parents, students, staff, and alumni to help determine strengths and weaknesses with regard to the IB standards and practices. ACS IB faculty members will also gather and process data as members of the following committees:

  1. Philosophy
  2. Organization
  3. Curriculum

Having completed the IB self-study questionnaire, from May 2019 through March 2020, the College is going to review the surveys, committee reports and other data. All IB policies will be reviewed and updated. ACS is going to submit the questionnaire responses, the Action Plan of IBDP improvement objectives for the next five years, and all necessary supporting documents to the IBO by April 2020. The culmination of the process will be a possible site visit by an IB evaluation team in April 2020.
