It was showed that indoor temperature, relative humidity and air movement were suitable in comparison with school indoor environment standard. Intensity of illumination was suitable in comparison with all schools, only exception 2 schools. In all investigated schools were adequate for carbon monoxide, sulfur dioxide and nitrogen dioxide, in which each ind(~)f environment standard (10ppm, 0.25ppm/hr, 0.15ppm/hr)but in 5 schools the carbon dioxide were exceeded for standard limit 1.000ppm of Korea. Indoor concentration of dust(PM-10) induced from respiration dust the standard of Korea (l50㎍㎥) at all schools.
