  Two evaluation formulas are derived for the Jack superpolynomials. The
evaluation formulas are expressed in terms of products of fillings of skew
diagrams. One of these formulas is nothing but the evaluation formula of the
Jack polynomials with prescribed symmetry, which thereby receives here a
remarkably simple formulation. Among the auxiliary results required to
establish the evaluation formulas, the determination of the conditions ensuring
the non-vanishing coefficients in a Pieri-type rule for Jack superpolynomials
is worth pointing out. An important application of the evaluation formulas is a
new derivation of the combinatorial norm of the Jack superpolynomials. We
finally mention that the introduction of a simpler version of the dominance
ordering on superpartitions is fundamental to establish our results.
