Abstract
We study the bound state spectrum of two classes of exactly solvable non-shape-invariant potentials in the supersymmetric WKB (SWKB) approximation and show that it is not exact. These examples suggest that shape-invariance is not only sufficient but perhaps even necessary in order that the lowest order SWKB reproduces the exact bound state spectrum.
