A record breaking donation will help StGiles purchase assistive communication technology.
Launceston Church Grammar School donated about $37,000 to the organisation after it raised the funds from its annual 80 kilometre walkathon.
It is believed to be the largest sum donated in the event's 56-year history.
A Tobiii Eye Gaze, valued at $23,500, will be purchased. It works through eye tracking and eye control to to combine speech generation for communication and environment control.
The students were motivated to raise the funds for people living with Cerebral Palsy by fellow student Lachie Moore who also has the condition.
Lachie believes it is important to raise awareness of the condition.
"Throughout my life, I have noticed how much of a difference it makes when people have an understanding of what Cerebral Palsy is, and equally, an understanding of how to treat those with the condition in daily life," he said.
StGiles chief executive Andrew Billing thanked the school and the grade 12 students for their efforts at an assembly on Thursday.
"Your gift will be enduring and will change lives,'' Mr Billing said. "Communication is a basic human right and the students' donation will allow young Tasmanians the chance to be heard.''
Launceston Grammar headmaster Richard Ford said the school was immensely proud of its Grade 12 students.
"Their courage and genuine desire to look beyond themselves is truly inspiring,'' he said.
