The American Customer Satisfaction Index (ACSI) is the national indicator of customer evaluations of the quality of goods and services available to U.S. residents. Since 1994, it has served as a uniform, cross-industry/government measure of customer satisfaction. A total of 10 groups, composed of eight program offices, EDFacts Coordinators, and Chief State School Officers, participated in the 2008 U.S. Department of Education Grantee Satisfaction Survey. All 10 groups had also participated in the 2006 and 2007 studies. Grantee satisfaction with the Department improved by two points in 2008. Three programs (Directors of Adult Education and Literacy; State Title V, Part A Directors; and EDEN/EDFacts Coordinators) have satisfaction with the Department above the federal government average. State Title I Directors and State Directors of Special Education rated satisfaction with the Department lower in 2008 than in 2007, but drops were not statistically significant. Three programs had significant increases in satisfaction with the Department: Chief State School Officers, EDEN/EDFacts, and Title III. Across all programs, complaints fell from 3% to 2%. While there have been improvements in 2008, the Department of Education should continue to focus on improving the high-impact, low-performing areas as first priorities. Technology and Online Resources are among the lower performing areas and both have considerable impacts on satisfaction. Within the area of Online Resources, improving the ease of finding materials online is recommended as a high priority. Five appendixes are included: (1) Questionnaire; (2) Non-Scored Responses; (3) Attribute Tables; (4) Verbatim Responses by Program; and (5) Explanation of Significant Difference Scores. (Contains 18 figures and 27 tables.)
