(a) The purpose of this part is to further the policy of the state to encourage and assist individuals who are blind or have other severe disabilities to achieve maximum personal independence through useful, productive and gainful employment by assuring an expanded and constant market for their commodities and services, thereby enhancing their dignity and capacity for self-support and minimizing their dependence on welfare and need for costly institutionalization.
(b) This part covers any political subdivision of the state having its own purchasing agency and includes governmental divisions of the state, counties, municipalities, school districts or any other public bodies supported in whole or in part by the general assembly. This part and participation under this program are optional for approved, nonprofit workshops for the blind in Tennessee and such workshops may proceed under part 2 of this chapter or under this part when seeking the purchase of their commodities and services. Participation under either program does not preclude approved, nonprofit workshops for the blind in Tennessee from participating in an alternative program at any time.
