What does a midyis score of 120 represent?

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.
