Description

A historical composite assessment scale that combines percentile-ranked mental and physical test results into age- and sex-normed scores for educational and vocational guidance.

Components

• A composite adolescent measurement scale built from averaged ten-percentile ranks on mental and physical tests: The scale ranks each child from one to ten on every mental and physical test according to the percentile in which the result falls, averages these ranks separately for physical measures (excluding height and weight) and mental measures, and places the average on general ten-percentile tables normed separately by sex and age. It was based on 750 fourteen-year-old children dropping out of school to work and 680 of the same children at fifteen, and places each individual 'in comparison with a large group of supposedly normal people of his own age and sex'. The article calls it 'a first attempt to formulate this kind of a standard, and is very rough in form'. (Woolley (1915))

Claims

• In Woolley and Fischer's comparison, 14- and 15-year-old school children outperformed working children of the same ages in all tests, physical as well as intellectual [+W]
• Composite mental test rank shows a large positive correlation with school grade, physical rank only a small one [+W]
• Exceptional mismatches between test rank and school grade are explicable by social circumstances [+W]
• Individuals' composite scale ranks are fairly constant from age fourteen to fifteen [+W]
• Mental and physical test ranks correlate positively but weakly, allowing rough sorting into five ability groups [+W]
• Graduating the scale by compositing the ten test-score distributions yielded an approximately normal ability distribution, and the age norms for ages 10 to 14 fell in almost a perfectly straight line [+W]
• Against Stanford Binet criteria for 300 grade 3–6 children, the mental index correlated .47, the educational index .52, crude score with mental age .80, mental with educational index .62, and Difference with I.Q. .21 [+W]
