<![CDATA[This study evaluates the contextual relevance of introducing Lean Construction to Vocational High School (SMK) students in Indonesia through a triangulation assessment of student workshop responses, curriculum alignment, and graduate employment data over three years. The novelty of this study lies in the simultaneous assessment of all three dimensions at the vocational education level, a topic that has rarely been addressed in the Lean Construction education literature. A short workshop combining a Lean Construction lecture and a LEGO-based Last Planner System® (LPS) simulation was conducted with 59 12th-grade students in the Building Construction, Sanitation, and Maintenance (KGSP) program at SMKN 26 Jakarta. Results indicated that 98% of students rated Lean Construction as important or very important, and 83.05% expressed interest in learning more. Curriculum analysis of official Learning Outcomes (Capaian Pembelajaran/CP) documents confirmed that Lean principles were not included in Phase E or Phase F Learning Outcomes. Three-year tracer study data (210 graduates from the 2023-2025 cohort) consistently indicated that the construction sector was the primary employment destination for employed graduates. This paper argues that the existing KGSP curriculum provides a strong technical foundation and can be enriched by integrating Lean principles into existing courses, particularly for graduates working in drafter and inspector roles.]]>
