The purpose of this paper is to emphasize the importance of early intervention. The purpose of early intervention in Taipei City is to help child development, promote parenting skills, and reduce educational and social costs. In order to meet these goals, parenting groups and Taipei City Council have made great efforts to make early intervention work in Taipei City. In April 1995, Taipei City Government started planning and setting up the service network. To date, Taipei City has set up one reporting and referral center, six community resources centers, 22 medical assessment and intervention clinics, 12 child development centers, one early intervention training center, three non-profit foundations and more than 300 inclusion schools, such as kindergartens and day care centers. With parent participation, professional devotion and Taipei City Government's commitment, the number of assisted children has increased from 98 to 2,523/year. By the end of 2006, Taipei had already funded 25,277 children. We estimate Taipei City early intervention services to have affected at least 75,000 persons, including development-delayed and disabled children, their parents, grandparents and siblings. We found that early intervention services help the children to build up self esteem, grow their potential, learn how to socialize, and receive an education, while the most important aim is to help them to reduce their level of disability or to prevent them from getting worse. At the same time, their families get support and a diverse range of services. An integrated early intervention program should include children, families, and multidisciplinary professionals. The system should therefore be more “family-centered” and “community-oriented” to provide appropriate services to children and families through a positive and aggressive attitude.
