Now in its third year, the course (which is run by the FAI in conjunction with Fingal County Council) sees 20+ players mix their academic subjects with FAI coaching courses, along with modules in Fitness Instruction, Media Skills and Personal Development, as well as football training and strength and conditioning work.
O'Neill spoke to the students, offering advice to the teenagers and answering numerous questions from those in attendance.
Speaking after the visit, Martin O'Neill said the course is a terrific opportunity for students to thrive both on and off the field.
"This gives the players an opportunity to improve all aspects of their game, while getting educated at the same time. I'd hope all the students make the best of the opportunities given to them."
Course Co-Ordinator Denis Hyland said the course has gone from strength to strength in recent years.
"We offer full-time football to the players along with furthering their education. In the first two years we have had 11 players capped at underage level, and some students from the first year have already made first-team debuts for SSE Airtricity League clubs.
Senior Sports Development Officer with Fingal County Council Niall McGuirk claims the course is giving students from Fingal the opportunity to thrive.
"We're delighted to be involved in the programme. It provides a pathway for players in Fingal the opportunity to fulfil their potential. Fingal County Council have been linked with the FAI for over a decade. We've reached countless people in the region because of that link."
