The Washington Declaration of Supervising Probation Officer (DSO) is a document issued by the Washington State Department of Corrections that outlines the roles, responsibilities, and expectations of probation officers in the state of Washington. The DSO is designed to ensure that probation officers provide appropriate supervision and services to those who are placed on probation or parole and are under the jurisdiction of the Department of Corrections. The document covers topics such as the types of supervision, reporting requirements, and performance standards that must be met by probation officers. The Washington Declaration of Supervising Probation Officer is divided into two main categories: adult and juvenile. The adult DSO outlines the supervision requirements for offenders 18 years of age and older, while the juvenile DSO outlines the supervision requirements for offenders under the age of 18. Both documents contain detailed information on the roles and responsibilities of probation officers, as well as the expectations for offenders. In addition, the documents provide information on the reporting procedures, the use of evidence-based practices, and the use of risk and needs assessments when determining an offender’s supervision plan. Finally, the documents outline the disciplinary actions that can be taken against probation officers who fail to comply with the requirements outlined in the document.
