We examine the census of star-forming galaxies and their extinction properties at redshift z~2, when a large fraction of the stellar mass in the universe formed. We find a good agreement between the X-ray, radio, and de-reddened UV estimates of the average star formation rate (SFR) for our sample of z~2 galaxies of ~50 Msun/yr, indicating that the locally calibrated SFR relations appear to be statistically valid from redshifts 1.5
