We present clustering measures of star-forming galaxies (Lyman-break galaxies) at redshifts z 3, 4 and 5 selected from Great Observatories Origins Deep Survey (GOODS). The redshift z 3 sample (U-band dropouts) is based on ultra-deep ground-based data and covers approximately 0.7 square degree down to a depth of R 26 mag (AB), extending these measures to a significantly fainter luminosity than previously done. The z 4 and 5 samples are based on HST/ACS imaging data and reach very faint flux levels (z 27). The three samples, thus, allow us to probe the dependence of the correlation function with both luminosity and redshift. We find that the correlation function varies mildly between redshift 3 and 5, in agreement with the CDM predictions of halo bias evolution. We also find that the correlation length depends on the rest- frame UV luminosity, implying that the star formation in these systems closely correlates with their host halo mass.
