We analyze the decay B0 --> K+ K- K0 using 383 million B-Bbar events
collected by the BaBar detector at SLAC to extract CP violation
parameter values over the Dalitz plot. Combining all K+ K- K0 events,
we find A_CP = -0.015 +/- 0.077 +/- 0.053 and 
beta_eff = 0.352 +/- 0.076 +/- 0.026 rad, corresponding to a CP
violation significance of 4.8 sigma.  A second solution near
pi/2 - beta_eff is disfavored with a significance of 4.5 sigma.
We also report A_CP and beta_eff separately for decays to
phi(1020) K0, f0(980) K0, and K+ K- K0 with m_{K+ K-} > 1.1 GeV/c^2.
