In this paper, we calculate the vector, axial-vector and tensor form factors of transition within the standard light-front (SLF) and covariant light-front (CLF) quark models (QMs). The self-consistency and Lorentz covariance of CLF QM with two types of correspondence schemes are investigated. The zero-mode effects and the spurious 
-dependent contributions to the form factors of transition are analyzed. Employing a self-consistent CLF QM, we present our numerical predictions for the vector, axial-vector and tensor form factors of 
(

transitions and 
induced

transitions. Finally, in order to test the obtained form factors, the semileptonic 
(
) and 
decays are studied. It is expected that our results for the form factors of transition can be applied further to the relevant phenomenological studies of meson decays.
