Non-verbal ability
This tests a person's capacity for logical thought. The scale is divided into five sets of 12 problems. To record answers, a number is written. No knowledge of English is required and the test does not therefore discriminate against people whose verbal skills are poor. It can even be used with people who speak no English - as long as they can understand the instructions!
Verbal ability
The verbal test was designed to measure receptive (hearing) vocabulary. This is an important facet of general ability. A pictorial method is used to assess the extent of someone's vocabulary. |

The assessor will say a word, and ask the person being tested to identify the appropriate picture. Again, this is the fairest judgement, as neither writing nor lengthy explanations are required.
Reading and Spelling
(separate tests)
The Wide Range Achievement Test (WRAT) is usually our test of choice, providing as it does a percentile score (50 being average) based on age (up to 70 years). Should anyone above that age need testing, we can re-configure the stats! |
