We compare constraints on the gluon polarization in the nucleon obtained in next-to-leading order global QCD fits to polarized deep inelastic scattering data with those coming from observables more directly linked to the gluon polarization, such as the double spin asymmetry measured by PHENIX at RHIC, and high-pT hadron production studied by COMPASS at CERN.pT hadron production studied by COMPASS at CERN.
