Originally published in 1935, Testing Children's Development from Birth to School Age highlighted the greatly increased interest in measuring the development of pre-school children by other means than the older, inadequate "intelligence tests". In the early part of the twentieth century the work done at the Psychological Institute of the University of Vienna under the general direction of Dr Karl Buehler had become favourably known throughout Europe and the United States. This was also especially true of the studies in child psychology directed by the authors Dr Charlotte Buehler and her one-time assistant, Dr Hildegard Hetzer. The book contains developmental tests for the first six years of life; techniques for testing small children; information on the construction of tests and the evaluation their results. Today it can be read and enjoyed in its historical context.
