    We report the final measurement of the neutrino oscillation parameters \(\Delta m^2_{32}\) and \(\sin^2\theta_{23}\) using all data from the MINOS and MINOS+ experiments. These data were collected using a total exposure of \(23.76 \times 10^{20}\) protons on target producing \(\nu_{mu}\) and \(\overline{\nu_\mu}\) beams and 60.75 kt\(\cdot\)yr exposure to atmospheric neutrinos. The measurement of the disappearance of \(\nu_{\mu}\) and the appearance of \(\nu_e\) events between the Near and Far detectors yields \(|\Delta m^2_{32}|=2.40^{+0.08}_{-0.09}~(2.45^{+0.07}_{-0.08}) \times 10^{-3}\) eV\(^2\) and \(\sin^2\theta_{23} = 0.43^{+0.20}_{-0.04} ~(0.42^{+0.07}_{-0.03})\) at 68% C.L. for Normal (Inverted) Hierarchy.
