  We compute the polarized splitting functions in the triple collinear limit at
next-to-leading order accuracy (NLO) in the strong coupling $\alpha_{\rm S}$,
for the splitting processes $\gamma \to q \bar{q} \gamma$, $\gamma \to q
\bar{q} g$ and $g \to q \bar{q} \gamma$. The divergent structure of each
splitting function was compared to the predicted behaviour according to
Catani's formula. The results obtained in this paper are compatible with the
unpolarized splitting functions computed in a previous article. Explicit
results for NLO corrections are presented in the context of conventional
dimensional regularization (CDR).
