The educational package was developed through a systematic multi-stage process, including defining objectives, reviewing and analyzing relevant theoretical and empirical literature, extracting key concepts, organizing content, and designing a structured package consisting of ten sessions. Each session was organized around four core components: objectives, structure, techniques, and assignments. To evaluate content validity, the package was reviewed by a panel of 11 experts in psychology, counseling, and education. The Content Validity Ratio (CVR) was calculated using Lawshe’s method to assess the necessity of each component, and the Content Validity Index (CVI) was calculated to assess relevance and clarity, following established content validity evaluation procedures.</p> <p><strong>Findings: </strong>The results indicated that all components of the educational package met or exceeded the minimum acceptable thresholds for content validity. CVR values for all sessions and components surpassed the critical value required for an expert panel of 11 members, indicating that the content was judged to be essential. Additionally, CVI values for all items were higher than the accepted criterion, demonstrating strong relevance and adequacy of the package content across objectives, structure, techniques, and assignments. Overall, the findings confirmed the internal coherence and content validity of the developed educational package.</p> <p><strong>Conclusion: </strong>The validated educational package demonstrates strong content validity and provides a theoretically grounded, structured, and culturally responsive framework that can be implemented in school settings to support female students’ psychosocial development, motivation, responsibility, and self-awareness.</p> https://qijes.com/index.php/ijes/article/download/1433/1455
