An Investigation of the Reliability of the French Pictorial Test of Intelligence

An Investigation utilizing ninety kindergarten and second grade students wan Initiated to assess the degree of reliability associated with the French Pictorial Test of Intelligence (PTI) and to study the level of difficulty and discriminative power of the Individual test Items. The test-retest correlations were .77 and .88 for the kindergarten and grade two samples, respectively, while split-half correlations ranged from .05 to .08. Sub-test Intercorrelations were quite high, In fact, much higher than those reported by French. Few items appeared to discriminate between the high-scoring and low-scoring subjects. The Items appeared to be arranged In ascending order of difficulty but while the Instrument appears to function adequately at the six-year level, the advisability for Its use at the eight-year level seemed subject to some doubt.
