The aims of the IDTA are to:

• Promote developmental TA to the public, including to individuals, groups, organisations and institutions
• Establish and monitor ethics and professional practices related to developmental TA
• Liase with appropriate professional bodies to stimulate, initiate and monitor standards of training and supervision being offered to students of developmental TA and of people working with the application of developmental TA
• Provide support and encouragement to meet the needs of practitioners and those in training who are involved in developing individuals, groups, organisations and institutions using developmental TA
• Promote ongoing research into developmental TA
• Provide a forum for those interested in ethical and professional applications of developmental TA
• Organise conferences and events so that developmental TA is disseminated and developed
• Stimulate and monitor continuous professional development of its members

The IDTA is affiliated to EATA - the European Association for Transactional Analysis.

Transactional analysis is a social psychology, a theory of human personality and a systematic approach for growth and personal change of individuals, groups and organisations. International qualifications are available (via the ITAA and EATA – the International and European TA Associations) in four fields – Organisational, Educational, Counselling* and Psychotherapy.

The term Developmental TA had now been adopted by the IDTA as this captures the emphasis on development rather than the psychotherapeutic focus on cure.
