Small galaxies are thought to be the main contributors to the ionising budgetof the Universe before reionisation was complete. There have been a number ofnumerical studies trying to quantify their ionising efficiency through theescape fraction $f_{esc}$. While there is a clear trend that $f_{esc}$ ishigher for smaller haloes, there is a large scatter in the distribution of$f_{esc}$ for a single halo mass. We propose that this is due to the intrinsicburstiness of star formation in low mass galaxies. We performed high resolutionradiative hydrodynamics simulations with Ramses-RT to model the evolution ofthree galaxies and their ionising efficiency. We found that the variability of$f_{esc}$ follows that of the star formation rate. We then discuss theconsequences of this variability on the observability of such galaxies by JWST.
