The purpose of this study was to investigate the effects and challenges of itinerant services for junior high school's gifted students in Changhua County. Participants were one administration staff member from the Special Education Division of Changhua County Education Bureau and three itinerant teachers for the gifted students. Interviews were conducted through the Internet with semi-structured questions and related documents were collected from the county government. The findings were as follows: (a) Itinerant teachers offered both direct and indirect services to the gifted students, of which were providing one-on-one learning sections to the students and professional counseling services to the school staffs and parents; (b) The learning activities which itinerant teachers offered were subject enrichment and special needs curriculum, such as independent study, affection education, leadership training and creative thinking; (c) Difficulties occurred on the lesson planning when a teacher's professional expertise differed from his/her gifted students; (d) The decline in the number of gifted students posed another challenge for maintaining the gifted itinerant services; and (e) The itinerant teachers' stress came from the numbers of students they served, difficulties of schedule arrangements, time spent on traveling, and a lack of support from schools. In conclusion, itinerant teachers did bring divertive enrichment services to the gifted students. However, there was a need for the County Government to solve the challenges which related to the gifted itinerant services. Based on the findings, this study offered some suggestions for the county education authority, the junior high school itinerant teachers, and further studies.
