From the Sticky in the RSE FAQ:
"EV-gain is tied to gaining EXP from battle, so you must defeat the opponent Pokemon to gain the EVs. This also means that any Pokemon that gains EXP from the battle gains full EVs from the defending Pokemon, whether they actually defeat the Pokemon, only participate in the battle (even without attacking), or are holding the EXP Share."
