He has extensive knowledge of monitoring and evaluation of programs and public health systems from working as an employee of State and County government and as a consultant to non-profits, and State, local and Federal agencies. At the State level, he was Director of Evaluation, Research and Client Data for the North Carolina Division of MH, DD and SA Services for over 12 years. He served eight years as Director of Outcome-Oriented Management in the Wake County (NC) Department of Human Services. Dr. Langmeyer maintained agency data sets concerning client data and provided reports from State and Federal data sets. As a consultant, he developed a capitation formula for NC Medicaid applied to Mecklenburg County utilizing the State Medicaid data base. He developed the Evaluation of NC Alternative Learning Programs surveys for every student enrolled, and information gathered on characteristics and performance in school for the NCSU Center for Urban Affairs and Community Services, under contract with the NC Department of Public Instruction. This involved conducting on site audits of a sample of alternative learning programs and creating three reports: 1) listing and characteristics of the ALPS's; 2) performance of students in the ALP's; 3) results of the visits As Research Associate on the proposed work, Dr. Langmeyer creates and maintains data sets and dictionaries, conducts statistical analyses, and produces summaries of results. He also provides assistance in developing data collection protocols and instruments under the direction of Dr. Laborde. Dr. Langmeyer provides valuable support in the evaluation of all our training interventions.
