The large value of θ13 recently discovered at reactor neutrino experiments has opened the door to determine the ordering of their mass eigenstates in the near future. However, since the neutrino mass ordering is a discrete parameter it is not clear whether the median sensitivity of a given experiment would coincide with the usual values reported in the literature. In this talk we present a summary of the different possibilities to determine the neutrino mass ordering in the near future, and we briefly discuss the statistical issues related to the significance of the signal for this measurement.
