Note on the comparative reliability of the Stanford-Binet below the age of six

Abstract

Using the correlation between first and second tests with more than 200 cases on the Stanford-Binet (up to the sixth year) and the retesting coefficient found by Good-enough for the Kuhlmann-Binet up to the six-year level, the author thinks that there is an indication that the reliability of the Stanford-Binet below the age of six is not much lower than that of the upper part of the scale.
