The MUonE experiment aims to measure with extremely high precision the leading-order hadronic contribution to the muon anomalous magnetic moment, related to the vacuum polarization (LO-HVP), which represents the largest uncertainty in the theoretical prediction of $a_\mu$. A first run has been conducted in 2021 to test the fundamental components of the detector, silicon sensors and related electronics, and the collected data are under analysis. The detector assembly and the tests will be carried on during 2022. In 2023 a Test Run is foreseen to validate the proposed methods and technologies, which will lead to the final proposal of the experiment. The current status of MUonE will be presented, including the available results of the analysis of the beam test data. These tests are fundamental to evaluate the capability of the apparatus to reach the needed accuracy of $10 {ppm}$ on the shape of the $\mu\mbox{-}e$ elastic scattering cross-section.
