Weakly Interacting Massive Particles (WIMPs,$\chi$) are candidates for Dark Matter. WIMPsearches at lepton colliders are complementary to searches at hadron colliders and direct de-tection, since they directly probe the coupling to electrons which a priori is independent of thecoupling to hadrons. Like at hadron colliders, WIMP pair production can be observed via anadditional visible particle, in particular a photon from initial state radiation ($e^{+}e^{-} \to \chi\chi\gamma$). Withthis technique WIMP masses to nearly half the centre-of-mass energy can be probed. Polarisedbeams are essential to reduce Standard Model backgrounds and to characterise the properties ofthe new particles in case a signal is discovered. Prospects for a mono-photon WIMP study atthe International Linear Collider will be discussed in the context of EFT. In addition, detectorrequirements critical to this analysis are discussed.
