Reconstruction and selection of physics objects in the ATLAS High Level trigger

We give an overview of the performance of the ATLAS trigger selections based on extensive online running during LHC collisions and describe the progress towards fully commissioning the individual triggers. Distributions of key selection variables are shown, calculated at the different trigger levels and compared with offline reconstruction. We include examples of triggering of Standard Model physics such as candidate W-boson decays. Comparisons between data and simulations are shown for important selection variables, already illustrating a good level of understanding of the detector and trigger performance. Finally we give a brief overview of plans for the evolution of trigger selections.
