Figure 16. The procedures were discussed beforehand with the Peace Corps personnel supervising educational activities on each island, and they explained the techniques and objectives to Marshallese teachers who actually conducted the tests. The tests were given in the regular classrooms, and prescribed time limits were used. The test results are recorded as raw scores in Appendix 2. The small numbers precluded any statistical analyses of these results, but it is apparent that the Ebeye group consistently scored considerably higher than the Rongelap group and that the scores for both groupsfell far below those recorded as “norms” in the manual. Observations during the testing indicated that, at Rongelap, neither the Marshallese teacher nor the subjects were very familiar with written examinations. Motivation was poor and understanding ofthe tests seemed marginal. The situation seemed better at Ebeye (Kwajalein Atoll), where more formal school classes are held. The exigencies of a field operation precluded improvementoftest conditions that would have permitted a moreleisurely and better understood examination. Under the circumstances, no quantitative interpretation of these test results seems justifiable. 26
