Abstract
Taking the FORS instruments as a representative case, I review the Calibration Plan for optical spectro-imagers currently offered at ESO, discussing various aspects related both to the scientific outcome and the instrument/site monitoring. I also describe ongoing and future calibration projects planned by the Instrument Operations Teams, trying to give an objective view on the limitations of the Calibration Plans currently implemented at ESO for this class of instruments.
