PTKR encourages new entrants to the profession and professionals with existing experience of working therapeutically with adults or others who have experience of working with children and adolescents.

PTKR has also adopted a Career Development Map and a four stage training model as a part of the Profession Structure Model. These provide considerable flexibility in terms of previous career background and aspirations to cater for as many people as possible.

A detailed model is currently being built for KOREA by PTI. The PTI Demand Model also calculates the number of practitioners required for small geographic areas such as regions, counties, cities down to the smallest census enumeration area. It is offered for use by policy makers and planners that are interested in the latent demand for their country, through PTI Consultancy Services.
