I believe that taking people through an understanding of their own personality is a responsibility that should not be taken lightly. It is a personal journey which can in many cases be life changing. It should be undertaken with care and integrity. It cannot be done with minimal knowledge and should be done by people who are committed to reaching the best outcome for their client and who are also continuing to improve and enhance their expertise.
Qualified professionals, particularly those who are members of their local or international professional associations, are best placed to offer a high quality service. The standard of the qualification programmes worldwide is very high. It is best to learn from the experts; those who have used this model for many years, are authors on their subject or who have served the type community well.
After qualifying it is best to undertake further study; become a Master Practitioner (US only), be involved in the many webinars now available internationally, join one of the many Associations for Psycholoigical Typenow set up worldwide, join a local chapter or interest group, make the most of the books, resources , social network forums and web sites. At all times make it a priority to increase your knowledge and understanding of Type.
