We investigate the Higgs boson production processes [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] in the littlest Higgs model with T-parity (LHT) at the International Linear Collider (ILC). We calculate the LHT model predictions on the production rate of these processes at the ILC in the case of (un)polarized beams and the signal strengths of the production processes [Formula: see text] and [Formula: see text] with Higgs decaying to [Formula: see text]. In the allowed parameter space, we find that the signal strengths [Formula: see text] is most likely approach to the expected precision of the ILC.
