The article discusses the features of applying the criterion approach to assessing the functional literacy of schoolchildren in computer science, the possibility of developing tasks based on the works of the studied scientists. In accordance with the updated educational program, the system of tasks aimed at the development of functional literacy of schoolchildren involves solving problems specific to specific life situations. This problem is usually associated with a new personal life for schoolchildren, work, recreation, and social life. The problems posed in the framework of tasks require the student to be able to work with information; manage many types of interrelated and interdependent objects and phenomena; describe the features of developing ways to solve problems in a new context. The possibility of implementing a system of multi-level tasks in improving the effectiveness of the lesson by creating a system of tasks for assessing the functional literacy of students in the study of computer science is determined. The possibilities of assessment aimed at increasing the interest and motivation of students by drawing up life tasks to improve the functional literacy of students are considered.

In the article, based on the criterion approach, the effectiveness of the system for assessing the functional literacy of students in computer science is proved by conducting a pedagogical experiment and conclusions are drawn about the results of practical work. The teaching experience consists of three stages. At the ascertaining stage, it was revealed to what extent the assessment tasks in computer science were compiled taking into account the directions of functional literacy of students. At the applicant stage, tasks and tasks were developed to assess the functional literacy of students based on a criteria-based approach in computer science. At the educational and control stage, the influence of the functional literacy assessment system, developed on the basis of a criterion approach in computer science, on the quality of knowledge and the methodology of teaching students in computer science was revealed. In addition, during the practice, the educational and methodological manual "tasks for assessing the functional literacy of students in computer science" was used. During the training in the control groups, the assessment of knowledge was carried out according to the traditional method, and in the experimental groups on tasks to assess the functional literacy of students based on the criteria approach.
