"She came to talk to the assembly this week - she is just a remarkable and inspirational young lady."
For Cates the timing was right to offer a few lessons in learning sign language as it was Sign Language Week.
She staged two sessions during the week and was delighted with the response from her pupils.
"It has gone really well and everyone has enjoyed it," she said.
With a smile she said she was delighted to see a couple of her library-based class later using sign language in the school canteen.
"They were ordering a pie - they did well."
She said while profoundly deaf, she had always wanted to enjoy and engage in life and would take that to another level after she leaves the college this year to study at Victoria University.
"I want to continue to build the bridge between deafness and hearing," she said, adding she would also take that into the community.
"I love helping others."
Her aim is to pursue a career working in textiles and design which she has excelled at.
She has also been a regular participant on the sports fields and courts.
"I love all sports."
Her only regret is that she will have to leave Sacred Heart this year.
"It is an amazing school and I've loved it here."
But she will leave a legacy behind as some of her younger sign language pupils, who have quickly picked up basic words and phrases, will very likely do their bit when Sign Language Week returns next year.
