Volunteer Information System Overview Willow Creek Academy was established as a public charter school in Colorado in 1995. Public charter schools operate as parent run schools without school boards. Parents of enrolled students elect a senate to set policies and provide oversight to the school administration and faculty. Willow Creek Academy's charter authorizes it to offer a core knowledge curriculum to grades K to 8 with two classes per grade consisting of 25 students per class. Other important policies established by the school senate involve uniforms, homework levels, and parental involvement. As parent run schools, charter schools lack resources provided to traditional public schools. To compensate for fewer resources, charter schools typically require parental involvement through various volunteer activities. Willow Creek Academy requires families to volunteer 40 hours during the school year. The school senate is interested in a computerized system to reduce the effort to track volunteer activities and communicate volunteer information to parents. The current manual system wastes volunteer time and provides only limited information about volunteer activities. Workflow Figure 1 depicts the volunteer process from needs identification to reporting of volunteer hours. At the beginning of each school year, volunteers are recruited for various activities. Recruiting occurs at the back to school night and then periodically through the school newsletter and informal communication. Most activities (Table 1) such as lunch room and traffic are standard activities with predictable schedules. Each year, new volunteer needs are proposed and approved by the parent teacher organization (PTO). Most activities have a coordinator who Volunteer Information System Overview Willow Creek Academy was established as a public charter school in Colorado in 1995.
