In 1913 the first applied psychologist took up his post with the London County Council. His job was to assess children for special educational programmes and develop tools to identify children who may need alternative kinds of education. With this post, the profession of educational psychology was born. The numbers of educational psychologists have steadily grown over the subsequent hundred years and the practices, roles and functions that they adopt have similarly developed. This book outlines the development of the profession in the United Kingdom during its first century of existence. It describes a number of different themes that have emerged over time and documents key points in the profession s development. Between each chapter is a vignette conveying personal accounts of the profession over the decades described.
