The literature shows a gap in science-specific assessments in this non-traditional context. The purpose of this study was to explore the application of authentic assessments to measure early childhood science understanding. Using a qualitative exploratory case study, the study was conducted at Sekolah Alam Tumbuh Kembang, Jakarta, for one semester. The subjects were 90 observation, interviews, and student portfolio analysis; the instruments were validated by experts. Data analysis used thematic methods. The results showed that authentic assessments were effective in capturing comprehensive and multidimensional science understanding. Project-based learning significantly supported science understanding and facilitated this assessment, aligned with the philosophy of nature schools. The contribution, the development of an integrated adaptive and pedagogical authentic assessment model for early childhood science education, enriches science and technology with a humanistic and holistic evaluation framework.
