A probation officer assistant performs a range of administrative services to support the federal court system. As a probation officer assistant, you work under the close supervision of a deputy officer and help ensure convicted criminals released on probation obey the law. Your job duties may include helping probation officers investigate cases by gathering information or creating reports, entering data into computers, and supervising low-risk offenders. To become a probation officer assistant, you typically need at least a high school diploma or GED certificate and on-the-job training. Some employers may require candidates to complete first aid or CPR certification and a national training program. Additional qualifications include prior clerical experience, excellent interpersonal and office skills, and an understanding of probation department functions and services.
