The calibrations of the CCD on HST WFPC2 are very important to improve the precision of astrometry and photometry. Many efforts have been devoted to the PSF (point spread function), row error of CCD and the correction of optical distortion. In recent years, higher precision is needed in some astrometry and photometry research, many further improvement of the method of reduction and calibration are carried out. These developments are briefly reviewed. Finally, some comments and prospective studies on these methods are presented.
