Purpose of the study: The current study was conducted to investigate Holland's circular order model of interest, congruence between career interest and career aspiration, and congruence impact on students' academic performance in an indigenous context. Methodology: Data have collected from 669 (356 boys & 313 girls) students studying in grade 10th from 16 high schools, 8 boys school (4 government & 4 private sectors), and 8 girls school (4 government & 4 private sector)-from significant towns of Gilgit division, Pakistan. Career interest was measured using the Urdu version of Career Key (Jones, 2010), students' obtained marks measured academic achievement in the last examination, and career aspirations were assessed by asking about aspired future careers from students. A randomized test of hypothesized order (Hubert & Arabie, 1987) was applied to determine the circular model, congruence was measured using Holland's (1963) first-letter agreement, and academic achievement of congruent, incongruent, and ambivalent groups of students was compared using one-way analysis of variance. Main Findings: The study's findings revealed that the results did not support Holland's circular order model of interest. The congruence hypothesis was partially funded, and the impact of congruence on academic achievement was fully supported in the present study. Gender differences were found in some career interests as well as in aspired occupations. The findings are discussed in a cultural context. Applications of this study: The results of the study are applicable and valuable for the educational institutes. In the present study, we have evaluated three assumptions of Holland's theory: circular order model of interest structure, congruence between career aspiration and career interest, and impact of congruence on students' academic achievement. Novelty: In Pakistan, career success and relevant domains are least explored by researchers. However, it is imperative to provide academic and career counselling services to ...
