This paper contributes to the history of nurture groups with a specific focus on the development of the Boxall Profile. It draws on the first-hand experience of the teachers involved in the Profile's origin with memories of the children who were responsible for the opening of the first non-pilot nurture group at Kingsmead Infant School, Hackney, during 1972-73. These memories are supported by the notes and the embryonic records from 1973-74 from which the Profile was derived, containing the nurture practitioners' intuitive responses, and how these were conceptualised, articulated and recorded. This 50th Anniversary Year of Nurture sees the publication of a new edition of the Boxall Profile Handbook (Revised) (Bennathan and Boxall 2019). A paragraph in Chapter 1, The Origins of the Boxall Profile, gives a brief overview of the Profile's development from a historical perspective. Chapter 4, How the Profile evolved, is Boxall's account of the Profile's process from conception to formal acceptance by the ILEA of its precursor, the Diagnostic Developmental Profile. This paper tells the human story behind these more formal accounts, and the way in which practitioners' careers were nurtured in the process. The learning involved in compiling the Profile had a major impact on their personal and professional development at a time before organised professional development was usual.
