The Midyis score is standardized, so 100 is average. Somewhere around 116 would be one standard deviation about average, so that suggests 120 is just above the cusp to be "above average". However, that is just observed score and there is a huge margin of error in such assessments as trying to measuring attainment in the brain is complex. So in reality, what the child actually knows will be somewhere between 108-132 midyis score. From the midyis score alone, it does seem reasonable to ensure that student is prepared to go through university.

What does a midyis score mean?
Apparently the mean score is 100, and the standard deviation is 15. This means that 67% of the population will score between 85 and 115. Higher scores are better. The company selling the midyis system will give, as well as scores, predictions of what the child should be able to achieve at GCSE level. Schools can then use this to a) track a child's progress compared with their theoretical capability predicted by the test, and b) to see if they have "added value" by raising the child to achieve more (or less) than predicted.
