1Some states, like California and Florida, have multiple QRIS operating on a county or local level.
As of fall 2016, there were 39 states with at least one QRIS. Note that some states, like Florida and California, operate QRIS on a local rather than state level so they have multiple systems.The first QRIS began operating in 1997. Relatively few QRIS became operational each year following that until a jump in 2006 to 2008. The rise in the number of QRIS over the past five years can be attributed, in part, to the federal Race to the Top-Early Learning Challenge grant program, which started in 2011 and includes QRIS participation rates as a performance metric. Over the past three years, the growth of QRIS has slowed, with only one or two systems being added each year.
