Which of the following is included in the "Significant changes since last JR" section?

The "Significant changes since last JR" section is specifically focused on tracking any alterations related to a child’s placement or goals for permanency. This aspect is crucial in child welfare as it highlights critical moments in a child's journey through the system, and understanding these changes enables policymakers and practitioners to assess whether the interventions in place are effective in promoting the child's stability and future wellbeing.

Changes in placement or updates to permanency goals are vital indicators of a child's current situation and future prospects. They can reflect broader dynamics within the family, the ability of caregivers to provide a safe environment, or shifts in the availability of support services. Thus, monitoring such changes helps ensure that the decisions being made are in the best interest of the child's long-term welfare.

While the other options might indicate improvements or developments in various areas such as education or family connections, they do not focus on the fundamental changes in care placement or long-term goals that are pivotal in assessing a child's welfare status.
