The ICSE Class 9 Computer Applications Syllabus 2026-27 introduces students to the fundamentals of computer programming, object-oriented concepts and Java. Prescribed by the Council for the Indian School Certificate Examinations (CISCE), the syllabus aims to develop students' logical thinking, problem-solving abilities and practical programming skills.
The Class 9 Computer Applications syllabus covers topics such as object-oriented programming, Java, data types, operators, input methods, mathematical library methods, conditional statements and looping constructs. Students will also learn about ethical issues in computing and practise writing Java programs through laboratory assignments.
The subject carries a total of 200 marks, divided equally between the written examination and internal assessment. Students can check the complete ICSE Class 9 Computer Applications syllabus for 2026-27 below, including chapter-wise topics, assessment requirements and evaluation criteria.
ICSE Class 9 Computer Applications Syllabus: Overview
The ICSE Class 9 Computer Applications subject focuses on building a strong foundation in Java programming. Students learn basic programming concepts and gradually move towards writing programmes using conditional statements, loops and nested loops.

Important Topics in ICSE Class 9 Computer Applications
Students should pay particular attention to the following concepts while preparing for their Computer Applications examination:
- Object-Oriented Programming: Understand the four principles of OOP, namely abstraction, inheritance, polymorphism and encapsulation.
- Java Programming: Learn the Java compilation process, JVM, source code, byte code and the features of Java.
- Data Types and Operators: Practise different data types, type conversions, operators and expression evaluation.
- Input and Output: Understand the Scanner class and its methods for accepting user input.
- Conditional Statements: Practise programmes based on if, if-else, nested if and switch-case statements.
- Loops and Nested Loops: Develop a clear understanding of for, while and do-while loops and practise number-based and pattern-based programmes.
ICSE Class 9 Computer Applications Syllabus: Internal Assessment
The ICSE Class 9 Computer Applications internal assessment carries 100 marks and is entirely practical-oriented. It focuses on helping students develop programming skills through regular laboratory assignments.Students are expected to complete a minimum of 20 programming assignments during the academic year. These assignments should reinforce the concepts taught in the classroom and involve designing, implementing and testing programmes.The syllabus provides the following suggested categories of practical assignments:

ICSE Class 9 Computer Applications Syllabus: Evaluation
The ICSE Class 9 Computer Applications internal assessment is evaluated by the subject teacher. The evaluation focuses on four major areas: class design, coding and documentation, variable description, and programme execution or output.The teacher assesses students' work based on the quality of their programming assignments and their understanding of the concepts covered in the syllabus.

The four evaluation criteria are explained below:
- Class Design: Students are assessed on whether they have used suitable classes, selected appropriate attributes and data types, implemented encapsulation and designed the interface properly.
- Variable Description: Students must provide the names, data types and purpose or description of the variables used in their programmes.
- Coding and Documentation: The teacher checks the quality and organisation of the code, choice of variable names, use of conditions and loops, error handling and proper documentation.
- Execution or Output: Students are assessed on whether their programmes run correctly and produce the expected output for the given sample inputs.
