  The aim of this study is to assess the capacity of the beam-matching of the characteristics of the Flattened (FF) and Unflattened (FFF) photon beam of the 6 MV energy of the Varian TrueBeam linac located at the Achifaa Specialized Center in Casablanca (Morocco). The dosimetric parameters in this research such as Percentage Depth Dose (PDD), surface dose, beam profile, Output Factor (OF), Transmission Factor (TF) and Dosimetric Leaf Gap (DLG) are analyzed by a non-parametric Kruskal-wallis test in order to study their degree of independence and a coefficient of variation a descriptive statistical analysis to measure the difference between these measurements. We observed a similarity between the FFF and FF beam data for surface dose and the beam profile for large irradiation field sizes; the output factor for small to medium field sizes, it was noted that the maximum depth dose (dmax) a..
