The knowledge and skill of Cardio -Pulmonary Resuscitation (CPR) are rather deficient for the junior high school students in Taiwan. Therefore, it is necessary to hold the related CPR training. The purpose of this study is to evaluate the effects of the CPR training program. A quasi-experimental research was used and fifty-six experimental subjects who attended the summer programs were educated by a four-hour CPR course from a junior high school in Hsin-Chu. In order to realize the education effects, two examinations, one before the CPR course and the other immediately after that, were performed. Moreover, far investigating retarded effects of the CPR course, an examination was held again after two months later. Experimental data was analyzed and revealed that: (1) The mean values are 46.79±15.22 for the pre-examination, 75.36±10.16 for the post-examination, and 71.33±15.59 for the test after two months. There are significant differences among the pre-examination, post-examination, and the test after two months [t(subscript (55))=-14.09, p<.001; t(subscript (53))=-10.39, p<.001]. (2) Both the score of the post-examination and the difference of the scores between the post-examination and the pre-examination for the third grade students are better than those for the second grade students [t(subscript (52))=-4.31, p<.001; t(subscript (52))=-2.35, P<.05]. (3) There is significant difference between the post-examination and the pre-examination of the intelligent performance [F(subscript (3,50))=3.32, P<.05]. The students with the worst intelligent performance have better score than those with the best intelligent performance. (4) The effects of the CPR program can last longer than two months.
