### Description

We redevelop the chiral kinetic theory (CKT) by exploiting the effective field theory method and find some disagreements at higher order of ($1/\mu$) from the earlier results. However, these disagreements are the same which have been pointed out by the off-shell effective theory formalism after identifying a cut-off. We address the discrepancies and by using the reparametrization invariance, we show that these disagreements are in fact expected due the choices of different degrees of freedom in effective theory and field theory. Further, we show that both methods yield the similar dynamics for chiral fermions.
