The grade equivalent score compares a child’s performance on a grade-level examination to the median (central most) score of other students on the same material in the test’s norming group.

How do you calculate Stanines?

1. The first 4% of ranked scores (raw scores 351-354) will be given a stanine score of 1.
2. The next 7% of ranked scores (raw scores 356-365) will be given a stanine score of 2.
3. The next 12% of ranked scores (raw scores 366-384) will be given a stanine score of 3.

How do you read Stanines?

Scale scores at each year level nationally are divided into nine levels of achievement, called stanines, with the lowest performance level being stanine one and the highest stanine nine. For example, you may be told that when compared with all Year 4 students nationally, your child is in stanine 7.

What is the stanine equivalent of a T score 60?

Standard Scores They have a preset mean and standard deviation. Standard scores most commonly used in schools are T-scores, stanine scores, and normal curve equivalent (NCE) scores. T-scores have a mean of 50 and standard deviation of 10. Thus, a student with a T-score of 60 is one standard deviation above the mean.
