  Lattice simulations on SU(2) and SU(3) gauge theories with matter fields in
the fundamental, adjoint and two index symmetric representations are needed to
determine if these theories are near or within the conformal window as required
for their applications in beyond standard model phenomenology. Simulations with
Wilson fermion action are subject to artifacts linear in the lattice spacing
$a$, and must be improved. We provide the necessary coefficients for
perturbative improvement of the boundary terms when using Schrodinger
functional boundary conditions and furthermore show that correctly implemented
O(a) improved actions are necessary for reliable results.
