The main purposes of this study were to analyze the correlation on frustration tolerance and life adjustment among fifth and sixth grade elementary students. A total of 300 questionnaires were dispatched, and 298 were valid. The questionnaire contained three parts: Personal background, Frustration Tolerance Scaleand Life Adjustment Scale. One Way ANOVA, t-test, Pearson correlation, and regression were used for analyzing data. The main results were as follows: First, in the aspect of frustration tolerance between fifth and sixth grade students, there were no significant differences on gender, grade, parents' social status and family patterns. Second, in the aspect of life adjustment between fifth and sixth grade students, there were significant differences on parents' social status and family patterns, but no significant differences on grade and gender. Third, the frustration tolerance significantly correlates with life adjustment, especially 'action' shows highest correlation, followed by 'preferred difficulty' and 'affection'. Fourth, among the action, affect and preferred difficulty, the three factors in frustration tolerance, the action was the most effective predictor of frustration tolerance.
