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

The RAN and RAS Tests are individually administered measures designed to estimate an individual's ability to recognize a visual symbol such as a letter or color and name it accurately and rapidly. The tests consist of rapid automatized naming tests (Letters, Numbers, Colors, Objects) and two rapid alternating stimulus tests (2-Set Letters and Numbers, and 3-Set Letters, Numbers and Colors). The Letters, Numbers, Colors, and Objects tests are comprised of five high-frequency stimuli that are randomly repeated ten times in an array of five rows for a total of fifty stimulus items. The 2-Set Letters and Numbers and 3-Set Letters, Numbers, and Colors tests are comprised of 10 and 15, respectively, high-frequency stimuli that are randomly repeated in an array of five rows for a total of fifty stimulus items. On all tests, the examinee is asked to name each stimulus item as quickly as possible without making any mistakes. Scores are based on the amount of time required to name all of the stimulus items on each test. The tests were normed on 1,461 individuals in 26 states; these norms are suitable for individuals from ages 5-0 through 18-11. 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. Ages: 5-0 through 18-11 Testing Time: 5 to 10 minutes Administration: Individual Features of the tests: Identifies students who may be at risk for reading failure Is quick to administer and easy to score Converts raw scores to percentiles, standard scores, and age and grade equivalents Is both valid and reliable for its state purpose Is appropriate for use with kindergarten students through high school students.  (Requires special credentials to access - Level 2.)
