The Pre-K/K 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, found under the section's Pre-K/K Assessment tab, 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 jurisdiction had implemented, or were planning to implement, an assessment for pre-kindergarten, and 31 had implemented, or were planning to implement, an assessment at kindergarten entry. To read the full report on these decisions, visit the CSAI State of the States webpage. (author abstract)
