Labour Minister Kelly Regan says regulations will now allow more apprentices to train under one journeyman in the metal fabricator trade.
The new regulations will allow three apprentices instead of just one, to train under one journeyman.
Regan says the changes will require the third apprentice to be more senior and in the final year of training.
In addition the province is reducing the amount of time it takes an apprentice to become certified from 8,000 hours to 6,000 hours and is increasing safety training.
The changes are to help align Nova Scotia with an agreement announced earlier this month aimed at making training, certifications and standards consistent across the four Atlantic Provinces.
