The officer then discloses the final report and sentencing recommendation to court through a mathematical system of allocating points. The total number of points allocated in each case lets the judge know what the presumptive sentence is. The officer also discloses the report to the defendant, and both attorneys. The probation officer must then be prepared to discuss the case with the sentencing judge in chambers or in court, to answer questions about the report that arise during the sentencing hearing, and, ultimately, to testify under oath in open court as to the basis for the factual findings and guideline applications recommended in the report.
