We examined a performance improvement package with components of feedback, goal setting, and prompting to generate additional revenue by improving the consistency of Medicaid billing submitted by 74 school psychologists serving 102 schools. A multiple baseline design across three service areas of a county school system demonstrated the effectiveness of the intervention to increase the number of school psychologists who completed their required documentation for Medicaid billing in a timely manner. This resulted in a substantial gain in income for the school district, which increased more than three times over baseline levels, with a small investment of additional time by all personnel involved.
