The implementation of Project-Based Learning through the Pancasila Student Profile Strengthening Project (P5) has been widely promoted to foster 21st-century skills and work readiness. However, systematic and decision-oriented evaluation models capable of generating evidence-based insights for curriculum improvement remain limited. This study addresses this gap by applying an Evidence-Based DIPPO Evaluation Model to assess the implementation of P5 and its impact on students’ competencies. This research employed a mixed-methods evaluative design based on a pilot (preliminary) study involving students, teachers, and school administrators. The evaluation was structured around the DIPPO framework (Design, Input, Process, Product, Outcome). Quantitative data were collected using structured questionnaires and pre–post skill assessments, while qualitative data were obtained through interviews, observations, and document analysis. Descriptive statistics, paired-sample t -tests, ANOVA, effect size analysis, and data triangulation were used to support evidence-based interpretation. The findings indicate strong performance in the Design, Process, Product, and Outcome dimensions, demonstrating high conceptual alignment, implementation fidelity, and positive learning outputs. Significant pre–post improvements were observed across all measured 21st-century skills, including critical thinking, collaboration, communication, creativity, and work readiness ( p
