Oregon Revised Statutes Procedure in Criminal Matters Generally § 135.917

(1) Courts having jurisdiction over the offense of possession of less than one ounce of marijuana shall designate agencies or organizations to perform the diagnostic assessment and treatment required under possession of marijuana diversion agreements described in ORS 135.907. The designated agencies or organizations must meet the standards set by the Oregon Health Authority to perform the diagnostic assessment and treatment of drug dependency and must be certified by the authority. Wherever possible, a court shall designate agencies or organizations to perform the diagnostic assessment that are separate from those that may be designated to carry out a program of treatment for drug dependency.

(2) Monitoring of a defendant's progress under a diversion agreement shall be the responsibility of the diagnostic assessment agency or organization. It shall make a report to the court stating the defendant's successful completion or failure to complete all or any part of the treatment program specified by the diagnostic assessment. The form of the report shall be determined by agreement between the court and the diagnostic assessment agency or organization. The court shall make the report of the diagnostic assessment agency or organization that is required by this subsection a part of the record of the case.
