Gifted and talented students are individuals who possess high intellectual potential and the ability to solve problems. Among the uniqueness of their psychological needs is perfectionism and distinctive thinking style. These students place high standards of achievement in their lives. This study aims to identify perfectionism level and dominant thinking style among gifted and talented Muslim students and to see the correlation between perfectionism level and thinking style. Researchers used the Measure of Contruct Underlying Perfectionism (M-CUP) questionnaire by Agnes Mariann Stairs (2009) to evaluate perfectionism and the instrument of Sternberg - Wagner (1997) translated and modified by Ruslin Amir (2007). Quantitative data was analyzed descriptively and inferred using SPSS version 22. Based on the findings of the perfectionism stage, the mean score of perfectionism for gifted and talented students was 195.03. It shows that perfectionism among gifted and talented students in this study is at a moderate level of score between 143 and 224. For thinking styles, 13 types of thinking styles have been measured which are legislative, executive, judicial, monarchy, hierachy, oligarchy, anarchy, global, local, external, internal, liberal and conservative. The dominant thinking style among students by sequence are executive thinking, judicial, monarchy, oligarchy, anarchy, global, local, external and conservative. Whereby non-dominant thinking style among the students are legislative, hierachy, internal and liberal. The study also found that there was no significant correlation or relationship between perfectionism and dominant thinking styles (executive, judicial, monarchy, oligarchy, anarchy, global, external, conservative and local). Some suggestions were made to get a better understanding and help students with perfectionism and at the same time increase their level of thinking styles in the quest of producing future gifted and talented Islamic scholar.
