The object of this project was to develop a culture-fair, nonverbal individual readiness test for disadvantaged preschool children. Two equivalent forms of the test were developed so that teachers could administer the first form to identify needs early in a preschool program, set up specific remedial programs for individuals, and use the second form of the test to assess the efficiency of the program and individual progress. A total of 6662 children in 364 Head Start and Day Care Centers were tested to refine and standardize Form A of the Test. Analysis and norming of Form B was carried on in 301 centers with 5271 children participating. Item analyses of both forms of the test were made. The data indicate that both forms of the test are sufficiently valid and reliable for use in an evaluation program for disadvantaged preschool children. Two-thirds of this report gives supplementary and appendix materials which include statistical tables, data of participants in the research project and facsimilies of Form A and Form B of the test developed.
