Abstract Quark--hadron duality of three proton spin structure functions g1, g2 and gT are discussed simultaneously. It is found that the onsets of the quark--hadron dualities of g1p, g2p and gTp are similar and they are expected to be at about Q2 ~ 2GeV2. In addition, our results show that the elastic peak remarkably breaks local quark--hadron duality.
