A possibility to measure the spin and spin-spin correlations of a chargino pair is e(+)e(-) -> (X) over tilde(1)(+)(X) over tilde(1)(+) -> ((X) over tilde(1)(0) q (q) over bar')((X) over tilde(1)(0)q "(q) over bar''') at future linear-collider investigated in the process energies. The total and the differential cross sections are calculated by the GRACE system which allows for the full spin correlation. Experimental sensitivity of the measurements are examined by assuming the limited detector resolution, the initial state radiation and the beam-beam effect (beamstrahlung). It is found that generally the spin-spin correlation can only be measured wih a lower sensitivity than the chargino spin itself. The dependence of the correlation measurements on the relevant SUSY parameters can be seen for a light (v) over tilde(e) case, but the situation becomes worse for a heavier (v) over tilde e.
