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.
