A search for the direct production of charginos and neutralinos in final states with three leptons and missing transverse momentum is presented. The analysis is based on 20.3 fb−1 of  s√s  = 8 TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with the Standard Model expectations and limits are set in R-parity-conserving phenomenological Minimal Supersymmetric Standard Models and in simplified supersymmetric models, significantly extending previous results. For simplified supersymmetric models of direct chargino  (χ˜±1)(χ~1±)  and next-to-lightest neutralino  (χ˜02)(χ~20) production with decays to lightest neutralino  (χ˜01)(χ~10)  via either all three generations of sleptons, staus only, gauge bosons, or Higgs bosons,  (χ˜±1)(χ~1±)  and  (χ˜02)(χ~20)  masses are excluded up to 700 GeV, 380 GeV, 345 GeV, or 148 GeV respectively, for a massless  (χ˜01)(χ~10) .
