This is the first time such a training course will be led and run by incumbent 4As creative directors and made available to people who are not in the industry.
The agency association is targeting young creative potentials, who are not working in advertising but wish to learn the essentials of working effectively in the creative departments of agencies.
Marc Lucas, D'Arcy creative director and chairman of the 4As Creative Committee, said the school would focus on creative thinking.
"This isn't a craft or design course. It's about concepts and ideas that produce advertising that helps drive the business of a client."
According to Lucas, a school is needed in the city because "Hong Kong is facing more and more competition, including in Guangzhou and Shanghai.
To be competitive, we must have the best ideas".
The 12-week course officially kicks off in July, with the programme covering outdoor, print, radio, television and integrated campaigns.
A final integrated brief also doubles as a contest to select the three best students who will receive special recognition and consideration for placement within 4As agencies.
Students will also learn the proper way of building their own portfolio of work as part of a job-hunting strategy.
