Thematic analysis identified initial indicators structured around ten curriculum components. In the quantitative phase, a three-round fuzzy Delphi technique was applied. Indicators were validated using fuzzy aggregation and defuzzification (threshold D ≥ 0.7). MAXQDA and SPSS were used for data analysis.</p> <p><strong>Findings:</strong> Out of 68 initial indicators, 5 were removed, 3 added, and 3 revised during the qualitative phase. In Delphi round two, 57 indicators were confirmed, and 9 were submitted to round three. Ultimately, 5 additional indicators were validated and 4 rejected. The final model includes 10 core components and 62 validated indicators.</p> <p><strong>Conclusion:</strong> The validated model provides a localized and structured framework for implementing project-based learning in elementary education and can guide curriculum design, content development, and teacher training.</p> https://qijes.com/index.php/ijes/article/download/1380/1407
