EVALUATION
The assignments / project work are to be evaluated by the subject teacher and by an External Examiner. (The External Examiner may be a teacher nominated by the Head of the school, who could be from the faculty, but not teaching the subject in the section / class. For example, a teacher of Geometrical and Mechanical Drawing of Class XI may be deputed to be an External Examiner for Class X Technical Drawing Projects.) The Internal Examiner and the External Examiner will assess the assignments independently.
Award of marks (20 Marks)
Subject Teacher (Internal Examiner) 10 marks
External Examiner 10 marks
The total marks obtained out of 20 are to be sent to the Council by the Head of the school.
The Head of the school will be responsible for the entry of marks on the mark sheets provided by the Council.
Aims for ICSE Technical Drawing Syllabus 2021
 To develop competence among the students to pursue technical courses like Engineering, Architecture, Draftsmanship Surveying and other professional courses.
 To understand basic principles of instrumental drawing drawn to scale and to acquire basic skills in the use of traditional drafting methods which would also be helpful in understanding computer aided designs.
 To acquire the basic knowledge in their applications in various fields.
Pattern for ICSE Technical Drawing Syllabus 2021
There will be one written paper of three hours duration carrying 80 marks and Internal Assessment of 20 marks.
The paper will be divided into two sections, A and B.
Section A will consist of a number of questions covering the entire syllabus. The candidates are to attempt three questions.
Section B will consist of questions which will require detailed answers. There will be a choice and candidates will be required to answer two questions from this section.
