AGATA is a modern γ -ray spectrometer for in-beam nuclear structure studies, based on γ -ray tracking. Since more than a decade, it has been operated performing experimental physics campaigns in different international laboratories (LNL, GSI, GANIL). This paper reviews the obtained results concerning the performances of γ -ray tracking in AGATA and associated algorithms. We discuss γ -ray tracking and algorithms developed for AGATA. Then, we present performance results in terms of efficiency and peak-to-total for AGATA. The importance of the high effective angular resolution of γ -ray tracking arrays is emphasised, e.g. with respect to Doppler correction. Finally, we briefly touch upon the subject of γ -ray imaging and its connection to γ -ray tracking.
