This study aimed to determine the present status of integrated curriculum (grades 1--3) with experience to support transformative learning practice at the school level. The national and locally prepared curriculum to teach the integrated curriculum with transformative learning theory was reviewed in different contexts. This study followed a critical case study design under a qualitative, transformative, and participatory methodology. This study was conducted in the Gorkha district, selecting the three schools and head teachers. Themes were determined based on observation and interview data. The finding indicates that the revised STEAM-based integrated curriculum tried to provide holistic, transformative learning practice by enhancing students' knowledge, skills and entrepreneurship capacity to culturally diverse students. However, head teachers and other teachers could not successfully develop an enthusiasm for its perfect implication in the school education system. Concrete professional training could support the implication of a newly revised STEAM-based integrated curriculum.
