In addition to the regular transportation of students to school, the Transportation Department of the Des Moines (Iowa) Independent Community School District provides transportation for alternative and special education programs, field trips, and after-school activities. The context evaluation (program description), input evaluation (staffing and budgeting), process evaluation (responsibilities), and product evaluation (accomplishments and improvements, needs/recommendations, and future plans) of Transportation Department activities in 1990-91 are described. The results indicate that in 1990-91: 94 district buses made a total of 918 trips daily to transport 7,500 students; the bulk of the Department's budget supports human resources, including 113 drivers; and the Department improved its physical facilities and implemented a computer program to help create bus routes and monitor inventory and maintenance records. Overall, the evaluation highlights several departmental needs: (1) a bus replacement schedule; (2) purchase of special education routing software; (3) additional or revised school board policies and procedures; and (4) improved communications with the rest of the school system. These needs will be addressed in the future as the Department continues to provide effective transportation. Nine tables and seven figures are included. Thirteen appendices present information on transportation schedules and services. (SLD)
