A study concerning the development and validation of an instrument intended to measure Goal II of quality education is presented. This goal is that quality education should help every child acquire understanding and appreciation of persons belonging to social, cultural and ethnic groups different from his own. The rationale for measurement contains only a sample of possible definitions of this goal and the inventory measures only a sample of possible behaviors. Based on the findings from grade 5 and grade 11 assessment data, a decision was made to use the nine items common to the inventories of both levels as the nucleus of an item pool for a grade 7 instrument. An item example is: How would you feel about sitting in class next to a person whose skin color is different from your own? Item construction was subject to the following restraints: the situation described in each item should be both possible and plausible and related to an individual stimulus rather than a class of stimuli. In order to score the sociometric instrument, the race, IQ level, socioeconomic level, religion and physical handicaps of each of the students in the two 7th grade classes were obtained from school records. It is concluded that this study present a model for future validity studies. The attitude measure produced can serve as a reasonably reliable and valid measure of 7th grade pupils' attitudes toward others who are different from themselves on the dimensions of race, religion, IQ, socioeconomic status, and physical characteristics.
