This is the presentation of the data of one case, selected by The Adolescent Growth Study Institute of Child Welfare, from a growth study consisting of approximately two hundred boys and girls. The data were obtained from interviews, detailed questionnaires, and individual and group psychological tests. Teachers, parents and fellow pupils were all investigated by these methods. In addition, detailed physical examinations were made regularly.

The selection of this particular case is interesting because the boy was emotionally and physically as well as socially handicapped. The correlation between these factors is clearly demonstrated. In spite of his poor adjustment in early adolescence he was able to take his place in the group during his senior high school years and through college. This was accounted for by his physical maturation and a change in the standards of the group both of which stabilized him emotionally.

The book is of value to all who are interested in the maturation of the adolescent.
