For the first time, measurements were made of the double-spin asymmetry A_et and the target single-spin asymmetry A_t in the exclusive reaction p(e,e'p)eta in kinematics dominated by the excitation of the S_11 (1535) resonance. Both A_et and A_t are found to be in agreement with the Eta-MAID model, which predicts strong dominance of S_11 (1535) excitation in the region studied, 0.3 < Q^2 < 1 GeV^2 and 1.49 < W < 1.59 GeV.
