The Pre-Kindergarten/Kindergarten Assessment tab of the State of the States section of the Center on Standards and Assessment Implementation (CSAI) website provides information on the design, development, and implementation of state-funded pre-kindergarten and kindergarten assessments that are intended to measure school readiness, both before and at kindergarten entry. The information is updated twice a year, in February and September. This CSAI Update provides results from the most recent scan of pre-kindergarten and kindergarten assessment systems in individual states, the District of Columbia, and U.S. territories. As of the February 2016 scan, 21 of these jurisdictions had implemented, or were planning to implement, an assessment for prekindergarten,and 31 had implemented, or were planning to implement, an assessment at kindergarten entry. States and other scanned jurisdictions use a variety of assessment tools that, for the purposes of this scan, were categorized into three types: direct, observation-based, and a combination of the two approaches. Some states do not have one particular pre-kindergarten or kindergarten-entry assessment but, instead, provide a list of approved or recommended assessments. In this most recent scan, CSAI began augmenting the state summaries with information about whether states have received funding under the U.S. Department of Education's Preschool Development Grant program, which includes both development and expansion grants.
