Ms Crocker gained the Certificate in Hairdressing (level 3), the equivalent of a first-year industry apprenticeship, then went on to complete the Certificate in Hairdressing (Practice), another level 3 qualification which is equivalent to the second and final year of an apprenticeship in a salon.
After graduating, she worked in a salon, but still that was not enough for her.
In May, she opened Classic Hair Design on Maunu Rd and works with former NorthTec student and beautician Carleen Still.
The hairdresser is also under taking training in small business ownership and ongoing professional development to keep her hairdressing skills sharp.
"It was exciting when I made the big decision to study, but it was scary when I got a few weeks in and thought, my gosh what have I done?" she added.
"At NorthTec I was known as camp mother to the younger girls, and everyone said I should be running my own place. In the end I just decided to go for it."
Her new business has been a hairdressing salon ever since it was built in the 1960s.
