Establishes a matching rate for states adopting home study in compliance with national standards.

Limits planned permanent living arrangements to children who have attained age 17.

Directs the Comptroller General to study: (1) the number of children in each state that are assigned a permanency goal of another planned permanent living arrangement for the most recent fiscal year for which data are available; (2) the ages, gender, race, and special needs of children whose permanency goal is another planned permanent living arrangement; (3) a review and analysis of court practices for determining that another planned permanent living arrangement is the appropriate placement for a child; (4) information with respect to foster youths' involvement in deciding to enter into a permanency goal of another planned permanent living arrangement; and (5) a summary of the reasons that reunification, adoption, kinship care, or guardianship were not found to be in the best interests of the child.

Requires a state to spend an amount equal to 20% of the amount of savings from adoption assistance de-linkage to provide post-adoption and post-permanency services to children and families.

Requires the state foster care and adoption assistance plan to: (1) commit the state to engage in public-private partnerships to promote evidence-based child-focused recruitment practices that focus measurable attention on the adoption of children out of foster care with an emphasis on those children most at risk of aging out of care, and (2) encourage placement of children with siblings.
