| Summary: | "The field of mental tests has been one of intense activities ever since the unprecedented success of the original Binet-Simon scale became generally known. This handbook is the result of seven years of continuous effort on the part of the writer and a number of assistants to improve the methods of determining degrees of mental development in children and adults, and to keep these methods at a point of maximum efficiency. The writer's duties as Director of Research at the Minnesota School for Feeble-Minded, and as psychologist for the Minnesota State Department of Education have furnished the immediate occasion for this effort. The foundation on which it rests, however, and the chief factor that has made the work possible, has been the recognition by the public that scientific research in an applied science with the aim of improving the methods and scope of its application pays.
