Transform classroom testing with a fast, standardized measure of general ability.

This guide explains how to create a mass-testing scale that is quick to administer and scoring is consistent across investigators. It outlines an Absolute Point Scale designed to reflect true ability, with careful attention to reliability and comparability.

The text details how to construct and validate a testing battery for groups, emphasizing simple responses, single correct answers, and scoring forms to speed up evaluation. It also describes the process of selecting, organizing, and comparing multiple tests to form a cohesive measure of general mental ability, based on data gathered from school-age pupils and preliminary investigations.

How mass testing is planned and implemented for efficiency and reliability
Principles behind an Absolute Point Scale and its zero point interpretation
Methods for combining and weighting multiple test elements to form a single composite
Strategies for evaluating item difficulty and diagnostic value to refine a testing battery

Ideal for researchers and practitioners seeking a rigorous approach to large-scale cognitive assessment.
