The progressive school of today is dominated by the belief that its purpose is to afford adequate opportunity for the highest development of every child. Its teachers are more highly specialized in subject-matter than ever before, and they are better trained in the principles of child psychology. However, their time is too limited, and their teaching load too great, to permit the intensive study of those individuals who still show the same problems of retardation and behavior deviations present under the old system. The need is definitely felt for a person, or a group of persons, with the time and the training to assist in the study of the problems arising both in instruction and in individual adjustment. Thus the educational counselor came into being. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
