This instrument assesses readiness for school in preschool disadvantaged children. Two forms, A and B, are available and it is recommended that one be used as a diagnostic pretest and the other as a progress measure. The test is an individually administered, non-verbal, untimed, but paced instrument. The child responds to questions, given in English, French, or Spanish, as appropriate, by pointing to one of four pictures or figures. The instrument tests the child's ability to recognize similarities, differences, the cardinal number of a set, and missing parts. No special equipment or training is necessary to administer. The teacher records responses on a separate answer sheet which is hand scored using a stencil. A copy of the answer sheet and stencil are included. The mean, median, standard deviation, quartile ranks, and percentile ranks for the norming groups are given in 6 month intervals from age 4.0 to 6.5. In validity studies, the average correlation of Form A with 17 commonly-used, standardized readiness and IQ tests was found to be .48; Form B, .53. The correlation with Head Start and day care teachers' ranking of readiness for entering public school was .68 for Form A and .63 for Form B. Split-half reliability on Form A was .87 and on Form B, .89. Parallel form reliability correlations for several populations are available. Complete information on the development of the test and supporting data is available in ED 037 253. (DG)
