Originally published in 1945, this title was intended mainly for use by teachers wishing to test children from ages 2-8 in order to establish their intelligence. Based on feedback to the author, this revised edition also includes tests for children up to the age of 15. The tests were used to give a teacher some idea of how much could be expected of each child, so that the class, when practicable, could be divided into groups of varying abilities, which could proceed at paces suited to their respective capacities. It was felt that if ‘inborn intellectual deficiencies’ could be identified at an early age the children could have ‘special treatment’, or in certain cases be placed in a ‘special school’, rather than be potentially written off as ‘lazy’. Today this can be read and enjoyed in its historical context.
