The document discusses performance appraisals and assessment centers. It defines a performance appraisal as a regular review of an employee's job performance and contributions. An assessment center is a technique used to measure a person's knowledge, skills, and abilities through exercises like in-basket tests, interviews, role plays and group discussions. Assessment centers are used for selection, identifying potential and talent, and determining training needs. While they provide expert evaluation of behaviors, assessment centers can be expensive and time consuming.
