本研究旨在探討「完美主義」及「成就表現」之相關情形，研究對象為國小舞蹈班與普通班學 生，三、五年級412位學生為樣本，以「完美主義量表」、「成就表現」為研究工具。「完美主義量 表」包含自我要求、過度在意錯誤、父母期望與父母批評四個分量表•「成就表現」則分成學科與術 科成就表現。
本研究透過描述統計、t考驗、二因子變異數分析，探討「班別」與「年級」在完美主義上的差 異；進而，以Pearson積差相關，探討完美主義與成就表現之相關情形。研究結果分述如下：
-、舞蹈班與普通班學生在完美主義傾向無顯著差異。
二、不同年級在「完美主義量表」中的^自我要求」、「過度在意錯誤」與「父母期望」分量表，達 顯著差異。
三、學生的自我要求越高，術科成就表現（民族舞蹈、芭蕾舞、現代舞）也越高。
四、學生太過度在意錯誤，數學成就表現會越低。
五、父母給予較多的負向回饋•學生在國語、數學、芭蕾舞的成就表現也越低。

The purpose of this study was to investigate the relationship between perfectionism and student achievement. Samples were 412 elementary school students in Taipei City and New Taipei City, including third-grade and fifth-grade students in dance-talented and regular classes. Research tools were Perfectionism Scale and achievements tests. The Perfectionism Scale included four subscales like high personal standards, concerns about mistakes, parental expectations, and parental criticism. Student achievements were academic achievements in mandarin and mathematics, and performing achievements in ethnic dance, ballet, modem dance, and improvisation.
Statistical analysis included descriptive statistics, t-test，two-way analysis of variance, and Pearson product-moment correlation. The main findings of this research were stated as follows:
1. There were no significant differences between gifted students with dance talents and regular students in the Perfectionism Scale.
2. There were significant differences between students of different grades in the Perfectionism Scale.
3. There were significant positive correlations between high personal standards and performing achievements in dance like ethnic dance, ballet, and modem dance.
4. There were significant negative correlations between concerns about mistakes and academic achievement in mathematics.
5. There were significant negative correlations between parental criticism and academic achievements in mandarin and math, and between parental criticism and ballet achievement.
