Alongside the likes of Ireland internationals Daryl Horgan and Matt Doherty all four previously participated in courses, before representing their country at senior level.
The two new locations in Dundalk and Waterford become the ninth and 10th FAI-ETB Centres in the country. There are three centres each in Dublin and Cork, while Limerick and Castlebar each have one centre.
Cabra Course Co-Ordinator Harry McCue said the two new locations will help players in the north-east and south-east of the country.
"The cooperation of the Education and Training Boards has been instrumental in the successful delivery of this programme for well over 10 years," said McCue.
"The courses which are unique and progressive and full-time are a great opportunity for the participants to advance their career in football to professional level.
"We have over 100 ex-trainees playing in the SSE Airtricity League around the country. It also gives trainees opportunities to access a Third Level education on successful completion of our syllabus, through the CAO system.
"In recent years, the courses have provided a solid platform for young people earn professional football contracts. This is most evident in Martin O’Neill’s current Senior National Team where a number of the squad are course graduates including Kevin Long, Daryl Horgan, Matt Doherty and Enda Stevens.
"It’s probably the nearest thing we have to a full time professional football apprenticeship course in the country and the level of coaches and tutors involved in delivering the programme are of the highest quality and include many high profile ex professional players and coaches."
