Abstract：Objective To understand the changing trends of teaching environment in primary and secondary schools in Inner Mongolia, and to provide a basis for further improving the teaching environment hygiene status of primary and secondary schools. Methods With a stratified random sampling method, we detected the teaching environment of classrooms of primary and middle schools selected in 103 counties and districts of 12 league cities in Inner Mongolia from 2019 to 2021. Results Among the indexes detected, the qualified rate of classroom noise was the highest (85.48%), but the conformity rate of desk and chair distribution was the lowest (22.05%). During the three-year period, the qualified rates of blackboard size, blackboard reflection ratio, average illumination of blackboard surface, average illumination of desk surface and per capita area of classroom showed upward trends year by year, and the differences in different years were statistically significant (χ2=189.403, χ2=29.720, χ2=122.207, χ2=49.762, χ2=8.279, P<0.01). The qualified rates of all indexes in suburban counties were all higher than those in urban areas except the qualified rate of blackboard size. The qualified rates of all indexes in middle schools were all higher than those in primary schools except the qualified rates of blackboard size and desk surface illumination and uniformity. The proportion of schools with flush toilets in 2021 increased by 9.3% compared with that in 2019, with a statistically significant difference (χ2=16.426, P<0.01). Conclusion The overall situation of classrooms and teaching environment of primary and secondary schools in Inner Mongolia is not optimistic. Although the qualified rates of most indexes show upward trends, the qualified rates of someindexes are low. It is necessary to strengthen the publicity and implementation of teaching environmental hygiene standards and improve the hygiene situation of teaching environment so as to protect the students’ physical and mental health.
