Mental and Scholastic Tests

This volume, one of vital importance to all interested in the problems and implications of mental testing, makes a timely reappearance in a second and enlarged edition. Here we have a detailed description and analysis of the investigations carried out by the author during his years spent as Psychologist to the London County Council.

To Dr. Burt falls the distinction of having been the pioneer in introducing in this country, the now generally accepted methods for the assessment of intelligence and educational attainments of children of all types. The volume is divided into three main sections or memoranda?the first dealing with Burt's revision for English children of the original Binet-Simon Scale of Intelligence Testing ; the second with the theoretical validity of the results, and the third with Burt's own tests of educational achievement. In the new edition of this book, the main bulk of the work is unchanged, but-several additions or appendices of great importance and interest to present day practice have been inserted.

In the second appendix he gives a detailed factor analysis of the Binet-Scale. In the remaining ones he deals
