The aim of this study is to analyze the IAQ concentrations of school rooms. In this study we measured and characterized IAQ at 440 school rooms from May 2009 to November 2012. At some school rooms, the PM10 concentrations exceeded the IAQ guidelines (100 ㎍/㎥) of the Ministry of Education. CO₂ concentrations at high schools were 1.18 and 1.06 times higher than that of the elementary and middle schools, respectively. CO₂ concentrations of some school rooms were exceeded the IAQ guidelines (1,000 ppm). Moreover, TBC concentrations at elementary school rooms were 1.23 and 1.33 times higher than that of the middle schools and high schools, respectively. TBC and HCHO concentrations did not exceed the IAQ guidelines. The classroom/non-classroom ratio of PM<sub>10</sub> was 1.06, while that CO₂ was 1.04, HCHO was 0.62, and TBC was 1.16.
