  We present a composite model of quarks with `effective supersymmetry'. The
model is based on the gauge group $(SU(2)_S \times SU(2)_M) \times (SU(2)_U
\times SU(2)_C \times SU(2)_T) \times SU(5)_{SM}$, where $SU(5)_{SM}$ is the
standard model gauge group. In the dynamical supersymmetry breaking sector
based on the gauge group $SU(2)_S \times SU(2)_M$, supersymmetry is dynamically
broken. The preon sector is constructed by the model proposed by Nelson and
Strassler. The fermion mass hierarchy among the up-type quarks originates from
the $SU(2)_U \times SU(2)_C \times SU(2)_T$ gauge dynamics. The supersymmetry
breaking is mediated to the minimal supersymmetric standard model sector by the
`preon' superfields which compose the quarks in the first two generations. To
obtain an experimentally acceptable mass spectrum, the scalar quarks in the
first two generations need masses of order 10 TeV, while the other
superpartners need masses less than 1 TeV. Therefore, the mass spectrum in our
model is one example of the `effective supersymmetry' model proposed by Cohen,
Kaplan and Nelson.
