The role of internal assessment in CBSE Class 10 exams is to evaluate the student's performance throughout the academic year. It serves as an important component in the overall assessment of the student's knowledge, understanding, and application of concepts. Internal assessment is conducted by the school and contributes to the final grades awarded in the board exams.

Types of Internal Assessment:
- Periodic Tests: These tests are conducted at regular intervals during the academic year to evaluate the student's understanding of the topics covered in the respective periods. They assess the student's knowledge, application, and problem-solving skills.

- Assignments: Assignments are given to students to enhance their understanding and application of concepts. These can be in the form of written tasks, projects, or practical work. They encourage students to research, analyze, and present their findings or solutions effectively.

- Activities and Projects: Students are often given various activities and projects related to the subjects they are studying. These may include practical experiments, fieldwork, surveys, presentations, or group projects. These activities help students develop critical thinking, teamwork, and practical application skills.

- Practical Examinations: For subjects like Science and Computer Applications, practical examinations are conducted to assess the student's hands-on skills, experimental techniques, and understanding of practical concepts.

Importance of Internal Assessment:
- Continuous Evaluation: Internal assessment provides a continuous evaluation of the student's progress throughout the year. It helps identify areas of strength and weakness, allowing teachers to provide timely feedback and support.

- Reduces Exam Pressure: Internal assessment reduces the burden of a single final exam determining the student's performance. It distributes the evaluation process over the academic year, making it less stressful for students.

- Encourages Active Learning: Through assignments, projects, and practical work, students are encouraged to actively engage with the subjects and apply their knowledge. This promotes a deeper understanding of concepts and enhances critical thinking skills.

- Develops Skills: Internal assessment activities and projects help students develop essential skills such as research, analysis, presentation, problem-solving, and teamwork. These skills are crucial for their overall academic and personal growth.

- Comprehensive Evaluation: Internal assessment provides a comprehensive evaluation of the student's performance, considering both theoretical knowledge and practical skills. It gives a more holistic view of the student's abilities compared to a single exam.

In conclusion, internal assessment plays a vital role in the CBSE Class 10 exams as it provides a continuous evaluation of the student's progress, reduces exam pressure, encourages active learning, develops essential skills, and offers a comprehensive evaluation of the student's performance. It is an integral part of the assessment process, contributing to the final grades awarded in the board exams.
