Pamphlet, Manual of Directions with Key, California Test of Personality - Secondary Series


This is the manual of directions (not the test itself) for one version of the California Test of Personality. The California Test Bureau not only published tests of intelligence (mental maturity) and achievement, but also measures of personality like the one described in this document. These tests were intended to measure personality adjustment and social effectiveness.

They came in several forms. The “Primary Series” was for kindergarteners and children in grades one through three (see 1990.0034.123). The “Elementary Series,” was for grades four through nine (1990.0034.124). The “Intermediate Series” was for grades seven through ten (see 1990.0034.125). The “Secondary Series,” for which this is the manual of directions, was for grades 9 to 14 [sic]. The Intermediate and Secondary series were published first, then the Primary and an adult form.

The authors the test were Ernest W. Tiegs (1891-1970), Willis W. Clark (1895-1964), and Louis P. Thorpe (1893-1970). Tiegs was a dean and professor of education at USC, Clark was director of administrative research for the Los Angeles public schools, and Thorpe was on the faculty in education at USC.
