The implementation of which law signaled a change in parent-professional relationships?

• A. PL 94-132
• B. Section 504 of the Rehabilitation Act
• C. PL 99-457
• D. Americans with Disabilities Act (ADA)

Answer: (C)

The implementation of PL 99-457 marked a significant change in parent-professional relationships within the context of special education. This law, enacted in 1986, expanded services to include children with disabilities from ages 3 to 5, as well as providing early intervention services for infants and toddlers. One of the most crucial aspects of PL 99-457 was its emphasis on parental involvement and collaboration between parents and professionals.

The law mandated that parents be active participants in the development of their child's Individualized Education Program (IEP) and other service plans. This requirement fostered a partnership model where parents and educators worked together toward common goals for the child's development and education. The legislation recognized the critical role parents play in supporting their child's learning and development, which strengthened the relationship between parents and educational professionals.

In contrast, the other laws mentioned, while significant, did not bring about the same level of change in the collaborative approach between parents and professionals as seen in PL 99-457. Thus, this legislation is pivotal in understanding the evolution of parent involvement in the special education process.
