The richness of the RHIC program and the capabilities of the PHENIX and STAR detectors enable the study of high-pT energy-loss as a function of centrality, momentum, and particle species. Signatures of energy-loss for high-pT particles in central heavy-ion collisions at the LHC and at top RHIC energies provide evidence for the formation of a QGP. The apparent turnoff of these signatures as the collision energy is reduced in the RHIC Beam Energy Scan would support the conclusion that a QGP is formed at top RHIC and LHC energies. Beyond this, the program facilitates the mapping of the QCD phase diagram and provides an extra dimension for constraining models and disentangling the collection of phenomena that effect particle yields and momenta. These phenomena include impact parameter dependent nuclear shadowing, radial flow, Cronin-like enhancement, baryon enhancement, hadronic energy-loss, and the primary target of study - partonic energy-loss.
