The direct measurement of the gluon polarization in the nucleon at the COMPASS experiment is discussed. Three complementary analyses are considered. All of them study using method based on selection of events originating from the Photon Gluon Fusion process. Most precise preliminary value of is obtained from the high pT pair channel for the region: .
