It explains why group testing can speed up assessments and how survey tests provide rough estimates of a whole population’s mentality. The book outlines three main uses: screening for feeblemindedness, classifying and evaluating schools, and informing social surveys. It emphasizes that group tests are not a substitute for detailed individual diagnoses, but they can reveal broad patterns that guide further investigation.

Structured in two parts, the text first describes the tests and their standardization, then gives a guide for applying them in real settings. Readers will learn what to consider when administering tests to large groups, how to interpret results in terms of percentile benchmarks, and how to compare performance across ages, classes, and schools. The material also discusses potential sources of error and the limits of reliability when judging individuals from group data.

How survey tests differ from individual intelligence tests and why they’re useful for groups.
Three practical applications: feeblemindedness screening, educational classification, and community surveys.
How to administer tests, score them, and interpret results using percentile-based indices.
Important caveats about accuracy, attention, and the limits of group data.

Ideal for educators, school administrators, and researchers interested in large-scale mental assessments.
