Currently, 49 states, the District of Columbia, and many U.S. territories are either planning, piloting or implementing Quality Rating and Improvement Systems (QRIS)—these are systems to assess, improve, and communicate about the quality of early education and care. Part I of this paper is a research study to clarify the different state QRIS models—what they look like, how the states describe their purposes, how they differ in inputs, activities, outputs and outcomes. The research findings were shared with a group of early childhood education experts with in-depth expertise in research, policy and practice at the national, state, local and provider levels. Part II of this paper shares the reflections of the expert panel. Part III offers recommendations to assist in advancing QRIS.
