Training in the INPP Method is offered in the United States in connection with the Institute for Neuro-Physiological Psychology in Chester, UK. The Institute for Neuro-Physiological Psychology (INPP) was established in 1975 by psychologist Peter Blythe Ph. D. The Institute was set up as a private research organization to investigate the effects of immaturity in the functioning of the central nervous system in children with Specific Learning Difficulties and adults suffering from Agoraphobia and Panic Disorder; to devise reliable methods of assessment; and to develop, supervise and evaluate effective programs of remedial intervention. INNP is a self-funding organization involved in research, clinical practice, and training in the methods developed at INPP.

Dr. Peter Blythe started to provide training courses for small groups of professionals in the United Kingdom and Sweden in the late 1970’s. During the 1990’s a formal training course in the methods developed at INPP was established in the United Kingdom.  This course is now available in Australia, Austria, Belgium, Czech Republic, Germany, Hungary, Italy, Luxembourg, Mexico, the Netherlands, Poland, Russia, Slovakia, Spain, Sweden, the United Kingdom, and the United States of America.  INPP-Chester is the certifying body for all countries providing training in its methods. Sally Goddard-Blythe is the current Director of INPP.

Since 1975, INPP has treated many thousands of children and adults with problems linked to immaturity in the functioning of the central nervous system. It has also carried out published research into the efficacy of methods developed at INPP.
