General Description of Test:The Vienna Test System is a computerised collection of tests and assessments that can be used alone or combined as batteries of tests. The system contains 59 multi lingual instruments covering work, health and education and categorised as Intelligence, General Ability, Special Ability, Personality Structure, Attitude and Interests and Clinical tests. Those tests that are produced in the English Language and have not been reviewed elsewhere in these reviews will be reviewed here as individual tests. The Calculating with Symbols (RIS) test is a 19-item computer-based stand alone test of non-verbal intelligence, specifically 'reasoning', as defined by Thurstone. The authors use Rasch scaling and base the test on the ability ‘to keep to restrictions for completing a task’ one of the three areas of reasoning described by Thurstone; the two other areas which are not assessed are inductive reasoning and deductive reasoning. The test is computer administered and scored and takes between 20 – 50 minutes to complete although it is not directly timed. The test taker is presented with a series of simple equations using meaningless symbols rather than figures and they have to identify (using the mouse) the right number (from 0 to 9) which corresponds to the symbol and would solve the equation. The test taker can choose the unsolvable option if they feel that the equation cannot be solved. A practice item is presented before testing begins. The test taker cannot move back to an item once they have answered it and no feedback is given during the test. Scoring is based on the number of items completed correctly which is normed using percentiles and T-values. The manual reports that test scores under 10 (raw score) indicate low ability and over 14 indicate above average ability. Also produced is a metric of time taken to complete the test although this does not appear to be used in the interpretation of test score. A computer-generated report of the scores is presented in a descriptive format. The test is available in 12 different language versions.
