Measuring Up: Equity Lessons from Australia’s Early Childhood Development Census

Australia is the only country in the world that regularly collects comprehensive information about the holistic development of every child entering its schools. This information, gathered through the Australian Early Development Census (AEDC), guides national and state policy and informs program development. Over the past 12 years, AEDC data have shown progress in reaching the most vulnerable children. The AEDC, along with population-based measurement more broadly, is useful for the United States because it can inform current discussions of equity in access to early childhood services.

New Evidence of the ACA’s Effect on People with Disabilities: Health Insurance, Employment, and Benefits

The Patient Protection and Affordable Care Act (ACA) of 2010 changed several aspects of the law concerning access to health insurance that were particularly salient for people with disabilities. These changes included removing limits on preexisting conditions, extending parent’s health insurance coverage of young adults until the age of 26, expanding Medicaid to more adults with low incomes, and making it easier to obtain affordable coverage outside the traditional employer-sponsored benefit system.
