Description
Using the Schroedinger functional (SF) with a single staggered fermion
field we calculate the SF coupling in four-flavour QCD for a wide range
of energies and lattice sizes up to $L/a=16$. Preliminary results for the
continuum extrapolation of the step-scaling function are presented. To
reduce cutoff effects, one-loop ${\rm O}(a)$ improvement has been implemented.
Various cross checks are made possible by the use of
two independent sets of lattices with either $T=L+a$ or $T=L-a$.
