1. Purpose of KIM Unified State Exam

The Unified State Exam (hereinafter referred to as the Unified State Exam) is a form of objective assessment of the quality of training of persons who have mastered educational programs of secondary general education, using tasks of a standardized form (control measurement materials).

The Unified State Examination is conducted in accordance with the Federal Law of December 29, 2012 No. 273-FZ “On Education in the Russian Federation.”

Control measuring materials make it possible to establish the level of mastery by graduates of the Federal component of the state standard of secondary (complete) general education in computer science and ICT, basic and specialized levels.

The results of the unified state exam in computer science and ICT are recognized by educational organizations of secondary vocational education and educational organizations of higher professional education as the results of entrance tests in computer science and ICT.

2. Documents defining the content of the Unified State Exam KIM

3. Approaches to selecting content and developing the structure of the Unified State Exam KIM

The content of the assignments is developed on the main topics of the computer science and ICT course, combined into the following thematic blocks: “Information and its coding”, “Modeling and computer experiment”, “Number systems”, “Logic and algorithms”, “Elements of the theory of algorithms”, “Programming” ", "Architecture of computers and computer networks", "Processing of numerical information", "Technologies for searching and storing information."
The content of the examination paper covers the main content of the computer science and ICT course, its most important topics, the most significant material in them, which is clearly interpreted in most versions of the computer science and ICT course taught at school.

The work contains both tasks of a basic level of complexity, testing knowledge and skills provided for by the basic level standard, and
and tasks of increased and high levels of complexity, testing knowledge and skills provided for by the profile level standard. The number of tasks in the CMM version should, on the one hand, provide a comprehensive test of the knowledge and skills of graduates acquired over the entire period of study in the subject, and, on the other hand, meet the criteria of complexity, stability of results, and reliability of measurement. For this purpose, CIM uses two types of tasks: with a short answer and a detailed answer. The structure of the examination work provides an optimal balance of tasks of different types and varieties, three levels of complexity, testing knowledge and skills at three different levels: reproduction, application in a standard situation, application in a new situation. The content of the examination paper reflects a significant part of the content of the subject. All this ensures the validity of the test results and the reliability of the measurement.

4. Structure of KIM Unified State Exam

Each version of the examination paper consists of two parts and includes 27 tasks that differ in form and level of difficulty.

Part 1 contains 23 short answer questions.

The examination paper offers the following types of short-answer tasks:

• tasks for choosing and recording one or more correct answers from the proposed list of answers;
• tasks to calculate a certain value;
• tasks to establish the correct sequence, presented as a string of characters according to a specific algorithm.

The answer to the tasks of Part 1 is given by the corresponding entry in the form of a natural number or a sequence of characters (letters and numbers), written without spaces or other separators.

Part 2 contains 4 tasks with detailed answers.

Part 1 contains 23 tasks of basic, advanced and high difficulty levels. This part contains short-answer tasks that require you to independently formulate and write the answer in the form of a number or a sequence of characters. The assignments test the material of all thematic blocks. In part 1, 12 tasks belong to the basic level, 10 tasks to an increased level of complexity, 1 task to a high level of complexity.

Part 2 contains 4 tasks, the first of which is of an increased level of complexity, the remaining 3 tasks are of a high level of complexity. The tasks in this part involve writing a detailed answer in free form.

Every year, demo versions of the current year's Unified State Exam are published on the official website of the FIPI.

On August 21, 2017, draft documents were presented regulating the structure and content of the KIM Unified State Exam 2018 (including a demo version of the Unified State Exam in computer science).

There are documents that regulate the structure and content of CMMs - codifier and specification.

The maximum initial score for the work is 35.

The total time to complete the work is 235 minutes.

Changes in the 2018 Unified State Exam KIM in computer science compared to the 2017 KIM

There are no changes to the CMM structure.

In task 25, the ability to write an algorithm in natural language was removed due to the lack of demand for this option by exam participants.

Examples of program texts and their fragments in tasks 8, 11, 19, 20, 21, 24, 25 in the C language have been replaced with examples in the C++ language, as it is much more relevant and widespread.

Demonstration versions of the Unified State Exam in computer science for grade 11 for 2004 - 2014 consisted of three parts. The first part included tasks in which you need to choose one of the proposed answers. The tasks from the second part required a short answer. For the tasks from the third part it was necessary to give a detailed answer.

In 2013 and 2014 in demo versions of the Unified State Exam in computer science the following were introduced changes:

• was in the second part of the work.

In 2015 in demo version in computer science was the structure of the variant has been changed and optimized generally:

The option became consist of two parts(part 1 - short answer assignments, part 2 - ).

Numbering tasks became through throughout the entire version without the letter designations A, B, C.

Was The form of recording the answer in tasks with a choice of answers has been changed: The answer now needs to be written down in a number with the number of the correct answer (rather than marked with a cross).

Was the total number of tasks has been reduced (from 32 to 27); was reduced from 40 to 35 maximum quantity primary points.

The number of tasks was reduced due to enlargement of assignment topics, information related to the topic and complexity of tasks in one position. Such enlarged positions became: No. 3 (storing information on a computer), No. 6 (formal execution of algorithms), No. 7 (technology for computing and visualizing data using spreadsheets) and No. 9 (transfer speed of sound and graphic files). IN demo version 2015 presented some examples of each of tasks 3, 6, 7 and 9. In real options for each of these positions it was proposed only one exercise.

• Was the sequence of tasks has been changed.
• That part of the work that contained long-answer assignments, hasn't changed.
