The syllabus lists the topics covered in the course, helping students plan their studies. Students should review the syllabus closely to grasp the course content.

The Advanced CNC Machining Technician course lasts two years and is available nationwide through a network of ITIs. The program includes two main parts: the Domain area and the Core area. The Domain area covers trade theory and practical skills, providing professional knowledge. The Core area focuses on employability skills and essential life skills. After completing the training, trainees receive a National Trade Certificate (NTC) from DGT, recognized worldwide. Students can also find the official ITI Advanced CNC Machining Technician syllabus in the brochure - Official ITI Advanced CNC Machining Technician Syllabus PDF

Course Structure of Advanced CNC Machining Technician

Here’s the training hours distribution for the Advanced CNC Machining Technician course over the two years:

Every year, students must complete 150 hours of On-the-Job Training (OJT) at a local industry. If OJT is not available, trainees must work on a group project instead.

Students can also take optional courses totalling up to 240 hours each year. These courses can help them earn a certificate for 10th or 12th grade, ITI certification or short-term courses.
