Using data from the CLEO II detector at the Cornell Electron Storage Ring, we measure scrB(τ−→h−π0ντ) where h− refers to either π− or K−. We use three different methods to measure this branching fraction. The combined result is scrB(τ−→h−π0ντ)=0.2587±0.0012±0.0042, in good agreement with standard model predictions.
