Entry evaluation for students

The American College of Sofia admits applicants in the 7th grade in the year they are applying and earn a minimum Grade Point Average (GPA) of 5.00 out of 6.00 (Very Good on the Bulgarian grading system). Applicants are ranked based on their results on the annual Admissions Exam.

Brief description of entry evaluation required

The ACS Admissions Exam consists of a short essay and an answer/multiple choice test section. The test section is responsible for 4/5 of the total exam grade, while the essay stands for 1/5 of it. The exam is conducted entirely in Bulgarian and is geared to the expected academic development of seventh-graders, therefore there is no need of special preparation. ACS does not organize preparatory courses, nor have we ever authorized any organization or individual to engage in such activity.

Waiting list

The college admits 180 applicants who have completed the 7th grade and have been ranked based on their results on the Admissions Exam. In 2022 there were over 700 applicants. After publishing the results, the first 110 boys and 110 girls are invited to enroll. The remaining applicants form the Reserves’ List. They can be invited if there are vacancies after the deadline for enrollment has expired. When enrolling applicants from the Reserves’ List, only their score at the exam is considered, not their gender.

Deadline for registration (new academic year)

Usually Admission Exam Registration takes place in February with the exam in March or April.

Qualities and characteristics best defining the school

The American College of Sofia integrates the values and best practices of American pedagogy with the rich educational traditions of Bulgaria and Europe. ACS seeks to develop critical thinking, lifelong intellectual curiosity, leadership, and collaboration among multi-talented students of various social, cultural, economic, and geographic backgrounds.

Teaching approach of the school

All ACS courses are advanced college/university preparatory, as the pace and depth is necessary in order for them to achieve two diplomas, and 100% go on to college/university. (In addition, classes within a Profile are considered honors level.) All students earn the American High School Diploma. In addition, Bulgarians earn the national Bulgarian Diploma, and international students earn the IB Diploma. ACS has five academic grades: 8th or “prep” grade (emphasizing intensive English training) and 9th-12th grades. All courses are taught in English except Bulgarian language and literature, foreign languages, Bulgarian geography and Bulgarian history. Bulgarian students choose a “profile”, an area of concentration, within the Bulgarian Diploma Program (11th and 12th grades), in which students go into more depth. All ACS students follow an English profile and choose one other profile from the following: Humanities, Foreign Languages, Natural Sciences (biology and chemistry), Mathematics & Physics, Entrepreneurship, Software & Hardware. All ACS students take extra mathematics every year beyond the requirements of the Bulgarian curriculum.
