This study utilizes Clark and Estes' (2008) performance analysis model, which systematically and analytically clarifies organizational goals to identify the current and preferred performance level within an organization. The purpose of this study was to identify the knowledge, motivation and organizational (KMO) needs of site administrators to effectively implement a Multi-Tiered System of Support (MTSS) at Westside High School in Downtown Unified School District. All six site administrators from Westside High School were interviewed and documents were analyzed to determine which of the twenty assumed KMO influences identified in this study were actual needs. Findings from this study showed that site administrators at WHS are somewhat motivated and capable of effectively implementing MTSS at their sites. However, ten of the twenty influences that were assessed were determined to be actual needs including four knowledge influences, two motivation influences, and all six organizational influences. This study makes recommendations for improving organizational performance by utilizing The New World Kirkpatrick Model to plan, implement, and evaluate the effectiveness of an MTSS training program designed to provide site administrators with the knowledge and skills, motivation, and organizational tools necessary to achieve their performance goals.
