In April 2001, 16-year-old TIGS student Andrew Jefferson suffered a fatal heart attack as he crossed the finishing line of a school cross-country race.

Since the death of the year 11 student, the school has installed two defibrillators which can also be taken to sporting events.

Head teacher of personal development, health and physical education Jay Tregonning said the previous head of the subject, David Dobinson, had pushed to get them to the school.

"We've got a defibrillator in the high school and one in the junior school, as well as a training defibrillator we use to demonstrate to our students how an automated external defibrillator works," Mr Tregonning said.

"For school carnivals we enlist the support of St John Ambulance services, and we also take our own defibrillators to some events as well."

CPR training is available for TIGS students as part of the PDHPE course, while all teachers are required to hold a CPR certificate - as is the case in the state's public schools.

"The majority of our PDHPE staff are also trained examiners with Royal Life Saving NSW," Mr Tregonning said.

"We aim to ensure all year 10 students get their CPR certificate as it's a great life skill to have."
