We present the first practical application of a non-destructive readout (NDRO) procedure in the context of randomized benchmarking of microwave single qubit gates. Results on an array of 225 stochastically-loaded Cs atoms using conventional readout demonstrate that our system is capable of performing below the 1x10-4 error threshold for fault tolerance. By increasing trap depth and reducing array size to 49, we perform NDRO by scattering light on a cycling transition for 10 ms to achieve a 99% detection fidelity and a 90% survival probability. This allows us to use post-selection methods and reduce our state preparation and measurement error.
