What educational movement began expanding the identity and practice of NASP around the year 2000?

The correct answer highlights the significant growth and diversification of the National Association of School Psychologists (NASP) regarding its identity and scope during the early 2000s. This period saw NASP expanding its role beyond traditional responsibilities to include a greater focus on advocacy, training, and collaboration with various stakeholders in education, mental health, and policy.

As school psychology evolved to address the growing diversity in student populations and schools' increasing emphasis on mental health, the NASP actively worked to reshape its identity to encompass these broader aspects. This included promoting comprehensive school psychological services and emphasizing the importance of social-emotional learning, intervention strategies, and culturally responsive practices.

While the other options mention significant legislative acts or movements, such as the reauthorization of IDEA and the passage of NCLB, they do not directly represent the internal changes and identity expansion within NASP itself during that period. Instead, they illustrate environmental factors influencing educational policy and practice, rather than specific movements that redefined the Association’s identity.
