The paper presents graduates results in computer science testing according to their dependence from students' gender, family socioeconomic status, and the type of prosperity of the locality of the school in Lithuania. It was found that the gender of the graduate does not affect the results in computer science test. However, the girls who chooses to take the Computer Science Matura Exam make up only 1/5 of all graduates. Meanwhile, the socioeconomic status of the student's family, the way of travel to and from school and the type of locality prosperity systematically does affect the results of computer science test of graduates. The entire population of Lithuanian general education school graduates (N = 2208) who chose to take the Computer Science Matura Exam in 2023 was investigated. Testing was administered centrally using a standardized test. As a hypothesis the insights were formulated on how to improve the computer science didactic system in the country's general education sector. On the basis of empirical data, conclusions and specific recommendations were formulated to improve the system of didactics of informatics in the field of general education in the country.
