Abstract: The direct pair-production of the superpartner of the $\tau$-lepton, the $\widetilde{\tau}$,is oneof the most interesting channels to search for SUSY in:the $\widetilde{\tau}$ islikely to be the lightest of the scalar leptons,and is one of the most experimentally chalanging ones.The current model-independent $\widetilde{\tau}$ limits come from LEP,while limits obtained at the LHC do extend to higher masses, but are model-dependent.The future Higgs factories will be powerful facilities for SUSY searches, offering advantageswith respect to previous electron-positron colliders as well as to hadron machines.In order to quantify the capabilities of these future $e^+e^-$ colliders,the ``worst-case'' scenario for $\widetilde{\tau}$ exclusion/discovery has been studied, takinginto account the effect of the $\widetilde{\tau}$ mixing on $\widetilde{\tau}$ productioncross-section and detection efficiency.To evaluate the latter, the ILD concept, originally developed for the InternationalLinear Collider (ILC), and the ILC beam conditions at a centre-of-mass energy of$500$\,GeV have been used for detailed simulations.The obtained exclusion and discovery reaches extend to only a few GeV below the kinematic limiteven in the worst-case scenario.The results of the detailed simulation study are then discussed in view of the experimental environmentof other proposed Higgs factory projects.
