A woman convicted of trafficking cocaine and sentenced to nine years in a Spanish jail has been given the green light to teach in Victorian schools.

The Victorian Institute of Teaching initially rejected Kim Salter's application to teach, saying it was not in the public interest for someone convicted of such a serious offence to work in schools.

Kim Salter has won the right to teach after being convicted of cocaine trafficking and sentenced to nine years in a Spanish jail.

But the 38-year-old successfully appealed the decision in the Victorian Civil and Administrative Tribunal, who ruled she would be a "great asset" in rural Victorian schools.

Ms Salter was introduced to international drug couriers when she travelled to Uganda in 2007. She "spent some months partying", and used drugs including LSD, marijuana, ecstasy, amphetamine, cocaine and magic mushrooms about five times a week, VCAT senior member Robert Davis wrote in his decision.
