Questions
Which syllabus is this course based on?
The NCVT / DGT Craftsmen Training Scheme (NSQF) Engineering Drawing syllabus for mechanical-group trades, Year 1. The centre follows the student's own ITI syllabus where it differs.
Do I need my own drawing instruments?
Yes, a basic set (mini-drafter or T-square, set squares, compass, scale and pencils) is needed for sheet work.
Is CAD taught in this course?
No, Year 1 drawing is done by hand on sheets; it builds the base for reading and drawing machine drawings.
How is the course assessed?
By sheet work marked against a rubric and viva-style questions, as in the ITI practical / AITT pattern.
