The Rust Advanced Numerical Reasoning Appraisal (RANRA) consists of 2 different but interdependent tests. The tests measure aspects of numerical reasoning requiring the individual to consider alternative solutions relative to given problems.
The individual’s task is to study each problem and evaluate how appropriate or valid these alternatives are. Test one assesses comparison of quantities, test two is concerned with sufficiency of information. There are 32 questions in total, taking about 40 minutes to complete.
Background to RANRA
RANRA has been developed as a companion tool to Watson-Glaser specifically to assess the higher level numerical skills required of managers today. Used either in combination with Watson-Glaser or on its own, the test assesses an individual’s capacity for deduction, interpretation and evaluation. It is not a computational maths test, but a sophisticated and highly developed assessment of internalised mathematical knowledge combined with real life problem solving. The test measures various aspects of numerical reasoning that together give a whole picture of the candidate’s higher cognitive facilities.
Using RANRA
-
Graduate recruitment- Employers are finding that today’s graduates are lacking anything more than a basic mathematical capability. This makes it very difficult to accurately select for management occupations that require more sophisticated numerical reasoning skills. Using Ranra can help identify graduates with the capability to learn and grow into more complex roles.
-
Selection prediction for experienced hires - RANRA can provide an estimate of potential success in certain types of occupation that require numerical reasoning capabilities. It can be used successfully as a selection tool within the recruitment process for those occupations. For example, hiring a sales manager whose performance is proven in meeting targets but an unknown quantity in so far as managing budgets, RANRA can give an indication of the candidate's capacity to develop into a more senior role with those requirements as part of the job specification.
-
Training and Development - RANRA can provide an accurate measure of existing numerical reasoning capabilities providing a benchmark against which training and development can be designed. This can be particularly useful in situations where team development is being investigated. RANRA provides for relative differentials in ability between individuals within a group being assessed, making it a valuable team development tool.
Reliability and Validity
Reliability was calculated using alpha, split-half reliability and standard error of measurement. The scores are: Alpha 0.78; split half 0.78 and SEM 4.69. While RANRA is relatively new compared to the WGCTA, validity across all areas of test evaluation (face, content, criterion, construct) exhibit high levels of confidence and are shown to be statistically valid.
The test conforms to British Psychological Society and American Psychological Association guidelines on personality test construction and use.
Accreditation Requirements
In order to receive the reports from the Intrinsic™, a British Psychological Society (BPS) Level B accreditation is required. If this is not held Getfeedback can provide a qualified consultant to provide feedback on the report.
Administration Options
Please note that in line with the test publisher’s guidelines for ability tests every possible step must be taken to ensure that the question sets are protected, and that the individuals completing the assessment are the individuals named. By purchasing this test you agree to ensure that everything possible is done to ensure this.
