The measurement of the forward-backward heavy-quark asymmetry at LEP i
s presented. The present status of the experimental tecniques is revie
wed and the LEP averages are given for the b and c asymmetries. Averag
ing all LEP results including the lepton asymmetries, the tau-polariza
tion and its asymmetry yields sin(2) theta(eff)(lept) = 0.2318 +/- 0.0
004. Combining this result with the SLC left-right asymmetry measureme
nt gives sin(2) theta(eff)(lept) = 0.2313 +/- 0.0003.
