Validity analysis in City C comparing the group scale against rankings collected from all teachers except some substitutes. The article prints an average correlation of r = .47 between test scores and teachers' ability rankings.
"Seventeen correlations were obtained between the test scores and teachers rankings of pupils according to ability; these rankings were obtained from all teachers in City C, except from some few substitutes who did not know the children well. The average correlation was .47."
