(RAN/RAS) Rapid Automatized Naming and Rapid Alternating Stimulus Tests

The RAN and RAS Tests are considered the “gold standard” of naming tests. They reflect three decades of clinical evidence and research across all parts of the United States, Canada, Europe, Israel, Asia, and Australia that have examined the relation between processing speed and reading. In addition, the tests are simple, fun, and quick to administer, making them important additions to any prediction battery or diagnostic assessment of oral and written language for children and adolescents. It is helpful for identifying students who may be at risk for reading failure.

On all tests the examinee is asked to name each stimulus item as quickly as possible without making any mistakes, such as a letter or color and name. Scores are also based on the amount of time required to name all of the stimulus items on each test. The group of six tests usually take about five to ten minutes to administer, depending on the age, language status (first or second language), and reading abilities of the child. This includes time for directions and practice items per test.
