We have presented deep optical and near-IR images of 15 GPS sources with previously unknown optical counterparts or undetermined morphologies. New or revised identifications and magnitudes have been obtained for 5 GPS galaxies. In total, spectra were obtained for 22 sources, resulting in 7 new GPS redshift determinations. The remaining empty fields and sources without proper redshifts are most likely intermediate redshift galaxies, based on their optical faintness and in some cases large R-K colors. Eight meter class telescopes are needed to complete identification and redshift determination of 1 Jy class GPS radio sources.
