Overview

Aptem Assess is a cognitive assessment tool that measures eight perceptual and cognitive processes that underpin an individual’s learning processes. It is based on proven assessment techniques that are used to assess cognitive neurodiversity.

Interpreting scores

Where a learner has completed a longer version of any of the eight ‘games’ then a ‘standard score’ between 50 and 150 is generated for that cognitive domain. The score will be shown by a marker on a horizontal chart.

The standard scores are mapped to the following categories:

• 50 to 84: ‘Support required’ - the learner’s performance is within the bottom 16% of learners for that domain.
• 85 to 90: ‘Slightly Below Average’ – the learner’s score is in the lower quarter (25%) of scores.
• 91 to 110: ‘Average’ – the learner has scored within the average range which accounts for half of all learners.
• 111 to 115: ‘Above Average’ – the learner’s score is in the lower range of the top quarter (25%) of scores.
• 116 to 150: ‘Well Above Average’ – the learner’s performance is within the top 16% for that domain.

How are standard scores calculated?

A standard score is a statistical measure of how an individual score compares to the mean score for a large group. It is based upon analysis of a large group of individuals’ scores from which is calculated the mean and standard deviation.

• Mean: this is the arithmetic average of all scores
• Standard Deviation: this is a measure of the spread of the scores

Aptem Assess scores are converted to a score range where the mean is 100 and the standard deviation is 15. These scores represent a learner’s performance on the ‘normal distribution’, sometimes called the bell curve, which are typically used to score cognitive tests and some examinations. This method of generating a standardised score accurately measures real differences test performance between learners.

A standard score of 100 represents a score which is exactly in the middle of the score range, i.e., better than 50% of the takers, and worse than 50% of the takers.

A standard score of 115 represents a score which is better than 84% of people and in performance terms is the lower boundary of the top 16%. The score represents a test performance that is plus one (+1) standard deviations below the mean (or average) score.

A standard score of 85 represents a score which is better than 16% of people and is the lower boundary of those with slightly below average or better performance. The score represents a test performance that is minus one (-1) standard deviations below the mean (or average) score

On any individual domain, most learners will have a score in the average range. The scores on each of the eight domains are independent of each other. This means that a learner could perform below average on one or more domains, and above average on other domains.
