Additional Notes

Apprentices must be at least 14 years old and meet the minimum educational qualification (typically 10th grade passed or equivalent, as per trade requirements). The course includes basic training (20-25% of the program) and on-the-job training, with a stipend provided as per NAPS guidelines (e.g., Rs. 7700 per month for one-year ITI trade passed apprentices, as per Gazette notification dated 25th September 2019). Successful completion leads to the National Apprenticeship Certificate (NAC) upon passing the All India Trade Test (AITT), recognized for employment in government and private sectors. The training emphasizes precision cutting and safety, addressing the high demand for skilled operators in India’s gem and jewelry industry, where 11 out of 12 diamonds globally are cut and polished.
