Ark. Code Ann. § 12-27-149

For the purposes of maintaining a sufficiently trained and specialized staff of probation and parole officers, the Division of Community Correction shall establish staffing guidelines using evidence-based practices to develop ratios between the number of high-risk, medium-risk, and low-risk probationers and parolees and the probation officers and parole officers assigned to the high-risk, medium-risk, and low-risk probationers and parolees in order to maximize the effectiveness of the monitoring ability of the probation officers and parole officers.
