We report measurements of the longitudinal double spin asymmetry for inclusive jet production using polarized pp collisions at {radical}(s) = 200 GeV at RHIC. Results from the 2005 and 2006 runs are presented. These results set substantial new constraints on the polarized gluon distribution in the proton over the kinematic range 0.02<x<0.3, when compared to next-to-leading order global analyses of deep inelastic scattering (DIS) data. The first measurement of the transverse single-spin asymmetry for inclusive jets at mid-rapidity is also presented.
