what is Iowa test

The Iowa Tests of Basic Skills (originally Iowa Every Pupil Test of Basic Skills) also known informally as the Iowa Tests or colloquially as ITBS tests, are standardized tests provided as a service to schools by the College of Education of the University of Iowa. Developers Everett Franklin Lindquist, Harry Greene, Ernest Horn, Maude McBroom, and Herbert Spitzer first designed and administered the tests in 1935 as a tool for improving student instruction.^[1]The tests are administered to students in kindergarten through eighth grade as part of the Iowa Statewide Testing Programs, a division of the Iowa Testing Programs (ITP).Over decades, participation expanded and currently nearly all school districts in Iowa participate annually in the program, as do many other school districts across the United States. In a cooperative relationship, participating schools receive ITBS test materials, scoring and reporting services and consultation in the use of ITBS for instructional purposes, and ITP utilizes participation by schools in research and test development.^[2] Both the ITBS and Iowa Tests of Educational Development(ITED) were revised in the 2011–2012 school year. They were rebranded the Iowa Assessments.^[3][4] In 2016-2017, Iowa Assessments will roll out their new testing program, Next Generation Iowa
