A brief scale of intelligence for use in school surveys.
Sidney Leavitt Pressey · Journal of Educational Psychology · 1920
T HE scale to be described in the present paper is the result of an effort to provide a readily-usable instrument which should make practicable two distinct, but related, types of study, in a school or school system.It was desired (i) to build a brief scale which might be used for the measurement of groups-classes, grades, schools or school systems-as regards the level and distribution of general ability among the children of these groups.Such a scale should be thus useful in making comparisons between children in different schools as regards the general intelligence of the pupils attending these schools, and as regards the grouping of the children into classes or sections on the basis of ability.Recent studies have shown marked differences between schools and school systems in this respect. 1 Results from the use of such a scale should also afford a valuable check to aid in the interpretation of finding's with tests of achievement. 2
