The head of the Australian Institute of Management WA will step down at the end of the year after 16 years in the role.
AIM WA's executive director Patrick Cullen said it was time to step down and move on to a new challenge after an enjoyable and successful term at the Institute.
AIM WA has grown its WA presence in recent years and is now the largest private sector provider of management and leadership development in the State.
The Institute is also involved in management and leadership development in Malaysia, Indonesia, China and India.
AIM WA chairman and president Keith Spence said the Institute had grown by a factor of four during Mr Cullen's leadership.
The move coincides with completion of the Institute's Six Star Green Star rated Learning and Development Centre, which will double AIM WA's future training capacity.
A national search will begin to replace Mr Cullen and it is expected that an announcement will be made later this year.
