Taking on a student was a huge undertaking but it allowed farmers to give back to the industry, she said.
About 70 people attended an open day about the programme on Wakefield Farms in Dipton the day after the information evening.
"It was awesome, we had a really great turnout," she said.
Most of the high school pupils were from Southland, but some were from Alexandra and Balclutha.
"There were a lot of young females who want to get into farming, which is cool," Priest said.
This year, seven students were being trained on farms in Southland.
She estimated that 13 students would be trained on Southland farms next year.
The aim was for students to be able to be trained on Otago farms in 2024.
Priest had been approaching southern high schools asking to talk to pupils about the programme.
