The self-appraisal window in myPerformance is open for Missouri S&T full-time benefit-eligible employees and will close Friday, March 31. While the self-appraisal is optional, it is recommended and some supervisors require one. Following the self-appraisal period, managers will complete their phase of the appraisal process.
