This paper is a brief psychometric review of the Cooperative Preschool Inventory (CPI-R), Revised Edition intended to supplement the review of CPI in the "Seventh Mental Measurements Yearbook." The 1970 revision of the CPI-R is a brief screening test for teacher-administered testing of three-to-six-year-old children. It is intended to indicate the degree of disadvantage which a child from a deprived background has, at the time of entering school, so that deficits can be remediated. The CPI-R has 64 items in four factor-analytically derived subtests: personal-social responsiveness; associative vocabulary; numerical concept activation; and sensory concept activation. Items are scored correct or incorrect, and responses are recorded in the four-page booklet. Examinees may draw in the booklet, and periodic reinforcement for correct answers may be given by the examiner. Studies of the CPI's validity are minimal. When it was administered to 317 North Carolina kindergarteners, there was found to be a socioeconomic component involved in test scores. There was also a correlation between CPI scores and intelligence quotient. Test norms are based on scores of 1531 children in over 150 Head Start classes, aged 3 to 6. Test reliability is reported as ranging from .86 to .92. (GDC)
