"I've changed so much for the better. Before the course, I wouldn't even know what to say in conversations, but now I'm able to have a good conversation with people, and I can get up in front of people and not have any nerves," Ben said.
"The value is almost immeasurable. I'm planning on doing a Bachelor of Science at University of Waikato, and I know now that anyone you meet you can turn into a friend. It's been amazing."
Acorn's donors, the late Mary and Roy McGowan, have been funding the scholarships since 2010.
"Thanks to this fantastic support from Roy and Mary McGowan, over the years more than 270 local students have had access to a youth version of a course that millions of people around the world have taken to learn skills for success in their professional and personal lives," Acorn Foundation chief executive Lori Luke said.
Acorn Foundation, Dale Carnegie BOP Waikato, and Priority One's InStep programme have long partnered to offer the youth-focused course, which provides methods to help young people improve both their self-confidence and personal communication techniques as they prepare to finish school.
