The Importance of a Low Span of Control in Effective Implementation of Evidence Based Probation and Parole Practices

This report explains why the current probation officer to supervisor ratio (7:1 span of control) should not be increased to a higher level due to significant impacts on the implementation and sustainability of evidence-based practices (EBPs) in the Community Based Correctional System in Iowa. Span of control is “the number of individuals, or resources, that a person can effectively supervise within a structured organizational, business of military setting” (p. i). Sections of this report following an executive summary are: the importance of a low span of control in effective implementation of EBPs for probation and parole; findings on the impact of this low span of control; probation officer competencies; application of theoretical span of control factors to an EBP probation and parole environment; and conclusions and considerations.
