It has been shown that the infinite well is a non-shape-invariant potential. By using the supersymmetry WKB approximation, the exact energy spectra for the infinite well are obtained. When the supersymmetry WKB approximation is exact, a necessary and sufficient condition for a potential to be shape invariant is an over-strong condition, this requirement should be weakened.
