Jets originating from the fragmentation of quarks and gluons are the most
common, and complicated, final state objects produced at hadron colliders. A
precise knowledge of their energy calibration is therefore of great importance
at experiments at the Large Hadron Collider at CERN, while is very difficult to
ascertain. We present in-situ techniques and results for the jet energy scale
at ATLAS using recent collision data. ATLAS has demonstrated an understanding
of the necessary jet energy corrections to within \approx 4% in the central
region of the calorimeter.Comment: Proceedings from XXXI Physics in Collisio
