PROBLEMIn 1963, Harris in his book on Children's Drawings(2) published a revision and re-evaluation of the Goodenough Draw-a-Man Test. The revision consisted mainly of adding 22 new scoring categories to the original 51 categories developed by Goodenough and in devising a Draw-a-Woman Scale which paralleled the Drawa-Man Scale. He presented two separate scoring systems, one for the Man and one for the Woman. I n addition, Harris developed a Quality Scale by which an I& for the Draw-a-Man and Draw-a-Woman Tests might be derived froin comparison with 12 quality plates. Harris(2) admitted, however, that "the saving in time by using the Quality scale is accompanied by an appreciable reduction in accuracy of measurement."This study investigated whether the method of scoring the Draw-a-Man Test, including the use of the additional categories devised by Harris, was significantly better than the Goodenough method of evaluating the same test. The directions used by Harris for the Draw-a-Man Test are the same as those used by Goodenough so it was felt a meaningful comparison could be made. PROCEDURE836 Draw-a-Man Tests drawn by white and Negro girls and boys ranging in age from 5 through 7 years were taken from the files of several New York school districts. These drawings had been administered as part of routine classroom testing situations and had been scored by the Goodenough scoring method by the various psychologists who had administered the tests. All of the children whose drawings were selected for study had been given individual Stanford Binet intelligence tests by school psychologists as part of the school program. Although a number of these children had been tested because they were school problems, the majority included in the sample came froni classrooms where the Binets had been routinely administered as part of an educat,ional and intellectual assessment project being conducted in the various schools.All 336 drawings were scored by the Harris method by a single psychologist. The first 30 drawings were rechecked by another psychologist to make sure no deviation from the Harris method occurred. The original Goodenough scoring done by the school psychologists was not changed.

PROBLEM AND METHOD The widespread use of the Goodenough Draw-a-Man Test and the variable results obtained with it provided the impetus for a long term study of reliability and validity.Reliability was determined by administering the Draw-a-Man Test to a11 kindergarten children in five New York State public schools and retesting the same group in the first, second and third grades. Twelve months intervened each time. The original group was composed of 280 white and Negro children from all aocioeconomic levels. Four years later, because of transfers and absences, only 112 children remained.Validity was measured by comparing the results of the Draw-a-Man Test with the results of the Stanford Binet Scale administered to 98 of the children, and with the results of the American School Achievement Test given in third grade. In addition the third grade teachers rated all the children on a nine point behavior adjust ment scale. Table 1 shows that although the kindergarten, first, second and third grade Draw-a-Man Test results all correlated highly with one another, none were as high aa the .94 obtained by Goodenough(*). The fact that the interval between Good-TABLE 1.

Studies by McCarthyca) and McCurdy'') who used longer intervals, one week and three months respectively, obtained lower correlations, .68 and .69. Our results indicate that the tests with the greatest time interval between them, namely the kindergarten and third grade, showed the lowest reliability, whereas those closest in time, namely the kindergarten and first, first and second, and second and third, showed the highest reliability.In terms of validity, all the Draw-a-Man Test results show a substantial correlation with the Binet and indicate that to a large extent both scales are meaauring the same function, namely intelligence. As expected, the Binet showed the highest
