  We discuss a test of the Standard Model fermion mass origin in models of
dynamical electroweak symmetry breaking. The couplings of composite
pseudoscalar resonances to top quarks allow to distinguish high-scale
Extended-Technicolor-type fermion mass generation from fermion partial
compositeness and low-scale mass generation via an induced vacuum expectation
value of a doublet coupled to the composite sector. These different possible
origins of fermion masses are thus accessible via weak-scale physics searched
for at the LHC.
