The present study was carried out for the period from July 14 through September 13, 1975 by means of questionaire distributed to 300 nursing students whose extent of satisfaction is known to be relatively low compared with other students of the different course of study by applying the perceptual orientation scale based on the principle defining that the e-ffectiveness in maintaining helpful relation with others in human society depends upon the per-cepthn possessed by individuals. The present study was intended to investigate the effectiveness of nursing profession for nursing students of the 4 - year system and 3 - year system nursing school and relationship between perceptual orientation and clinical achievements, thereby, attempting more efficient a-pplication of the perceptual orientation scale. The results obtained are summarized as follows: 1. There was observed no significant difference in perceptual orientation between the nursing students of the 4 - year system and 3 - year system nursing schools. 2. 'There was observed significant correlation between the perceptual orientation and clinical achivements of the nursing students. 3. In the comparison of the perceptual orientation point and mean value by school, significant difference was observed between schools other than B and C schools of the 4 - year system. 4 . Marked correlation was observed between the perceptual orientation and clinical achievements of the students of 4 - year system nursing courses. 5 . Low correlation was observed between the perceptual orientation and clinical achievements of the students of the 3 - year system nursing school.
