  In order to probe the factorization hypothesis in color-suppressed $B
\rightarrow \psi (2S) + K (K^*)$ decays we have studied three ratios: $ R
\equiv B (B \rightarrow \psi K) / B (B \rightarrow \psi(2S) K)$, $ R' \equiv B
(B \rightarrow \psi K^*) / B (B \rightarrow \psi(2S) K^*)$ and $ P_L^\prime
\equiv \Gamma_L (B \rightarrow \psi(2S) K^*)/\Gamma (B \rightarrow \psi(2S)
K^*)$ in several scenarios for the $ q^2$-dependence of the form factors
involved. We find that measurements of R and $R' $, which exist, do not yield
scenario-independent tests of factorization. However, the predicted range of $
P_L^\prime$ in all scenarios lies in a narrow range, $ 0.50 {\
\lower-1.2pt\vbox{\hbox{\rlap{$<$}\lower5pt\vbox{\hbox{$\sim$}}}}\ } P_L^\prime
\leq 0.67$, and could test factorization.
