This final report describes activities of Project PARTnership, a 3-year demonstration program to develop the self-determination and self-advocacy skills of young people with disabilities through increased participation in the arts. Key program elements included: (1) development of a new course and adaptation of existing curricula to increase accessibility of arts education to students with disabilities; (2) training of school faculty, community arts leaders, and parents to increase their understanding of the value of arts education for students with disabilities; (3) involvement of artists with disabilities as performers, trainers, role models, and mentors; (4) establishment of a support network to encourage students with disabilities to pursue their interests in the arts and to promote their integration into school and community arts programming; and (5) development and implementation of an Individual Arts Education Plan as part of each student's Individual Education Plan process. The project coordinated with Very Special Arts organizations and implemented the program at sites in Louisiana; Ohio; Washington, D.C.; Nevada; New Hampshire; and New Mexico. The core course involves 20 to 50 sessions of instruction in the visual arts, dance and creative movement, music, drama, or creative writing. The project also developed an instructional kit, a videotape, and a teacher's visual sampler. Most of this document consists of a third-party year three evaluation report and final reports from the nine implementation sites. The visual sampler, which is appended, provides an illustrated introduction to the program. (DB)
