In this paper the Carey non-conforming ยฎnite element is considered for solving eigenvalue problems of the second-order elliptic operator. Based on an interpolation postprocessing, high-accuracy estimates of both eigenfunctions and eigenvalues are obtained: Here, P 2 2h is an interpolation operator,
