Abstract: OSIRIS is the first light instrument of the 10.4 m GTC. Apart from standard imaging and spectroscopic observing modes, multi-object spectroscopic observations with OSIRIS instrument were initiated in March 2014, with extraordinary success both in the users' demand as well as in the data quality obtained. In this contribution we give a brief description of the process for requesting and defining MOS observations with OSIRIS. We present some numbers on the accuracy obtained in the mask design and on-sky positioning, based on real data obtained at the telescope during the first year of operation of this observing mode.
