First published in 1950, Long Term Results of Infant School Methods was written to explain and summarise the results of Gardner's experiment to test the extent to which the effect of different styles of Infant school education, "experimental" or "control", would also be apparent at a later stage.

The book details how the tests and the schools involved were chosen; the different types of tests conducted and their respective aims; and a summary of Gardner's conclusions. It will appeal to those with an interest in the history and theory of education.
