Level of Service Research Library

At MHS we know that Public Safety professionals value assessments with large, representative normative samples that have proven validity. For legal reasons, public safety organizations require tools that have independent reviews and where research has been replicated by other experts in the field. We are proud to provide you with reliable assessments such as Level of Service/Case Management Inventory™ the (LS/CMI™), and the Level of Service Inventory–Revised ™ (LSI-R™) that work and are centered on evidence-based practices.

We have created an online resource library of research papers, journal articles, and media reports that site MHS assessments. This helpful online resource was designed to answer your questions, provide background information, and give you access to the large body of research that exists for these powerful tools.
