Culture is the soul of a nation, and it is the inexhaustible power of national development. The inheritance of minority culture is the core goal of ethnic culture in school. The purpose of this scope review is to gain a more comprehensive understanding of the current situation, problems, countermeasure suggestions to solve the problems, and development paths of ethnic culture in schools. The research method of scoping review was used to screen the relevant literature on ethnic culture in school that met the inclusion criteria, extract the basic information of the literature (author, time, title) and relevant information of the study (research purpose, research method, main problems, improvement strategies), and summarize and analyze the extracted contents. The result is that 10 papers meet the screening criteria, and the main regions involved are mainly Guizhou, analyzing the problems and improvement strategies of ethnic culture in schools. It is concluded that theoretical and practical studies of ethnic culture in school are relatively abundant, mostly focusing on feasibility and effectiveness studies, practice and reflection studies, and case studies, but most of them are superficial and repetitive. There are even fewer studies based on intelligent and digital perspectives, so further research is needed in this area.
