The lawyer is a member of the legal profession who has important roles in adjudication in the court on behalf of his client. He must be responsible for his client's reputation, credit, property, right, duty and liberty. It is therefore necessary to train the lawyer to have special and adequate knowledge, skill and morale for his profession. The purpose of this research is to assess the administration of the training of the lawyer's profession in Thailand in the areas of organizers, courses and methods of the training, compared with those of the judge and prosecutor in Thailand and of the lawyer in England, United States of America, France and Japan, to find out how much it meets with standards of training and lawyer's profession. The result of the research has revealed many deficiencies due to the lack or permanent responsible personnel of the organizers, improper courses which do not cover and emphasize the contents needed for the functions, insufficiency of time and inefficient methods of the training. In conclusion, the writer has recommended guidelines for improvement of the organizers, courses and methods of the training of the lawyer's profession.
