Results of a blind test of photometric redshift predictions againstspectroscopic galaxy redshifts obtained in the Hubble Deep Field with the KeckTelescope are presented. The best photometric redshift schemes predictspectroscopic redshifts with a redshift accuracy of |Delta-z|<0.1 for more than68 percent of sources and with |Delta-z|<0.3 for 100 percent, whensingle-feature spectroscopic redshifts are removed from consideration. Thistest shows that photometric redshift schemes work well at least when thephotometric data are of high quality and when the sources are at moderateredshifts.Comment: 14 pp., accepted for publication in A
