Are age equivalent scores misleading?

If a 4-year-old receives a raw score of 68, his age equivalency would be 3 years old. These types of scores are often very misleading though because this does not mean the child is functioning at the level of a 3-year-old.

What is a grade equivalent?

GRADE-EQUIVALENT SCORES The Grade-Equivalent score compares your child’s performance on grade-level material against the average performance of students at other grade levels on that same material and is reported in terms of grade level and months.

a method of standardizing a test by establishing norms based on a sample of children who are of the typical chronological age for their grade in school.

How do you interpret age equivalent scores?

Simply put, an age equivalent is a comparison of your child’s performance compared to age groups whose average scores are in the same range. For example, if your 9-year-old child scores a 42 raw score on a test, and that score is average for 8-year-olds, their age equivalent score would be 8.

Is a standard score of 85 average?

For example, a standard score of 85 (16th percentile rank) on a test may be “average,” “low average,” or even “below average,” depending on the test publisher.

How do you calculate equivalent grade?

Grade equivalent scores can be calculated for a test by finding the median (i.e., the 50th percentile) score obtained by children at each grade level on that test. Children who earn the median raw score for a given grade level are assigned a score equivalent to that grade level.

How do you read equivalent grades?

The digit(s) to the left of the decimal represent the grade. The digit(s) to the right of the decimal represent the month. We assume 10 months per school year. The GE of a given raw score on any test indicates the grade level at which the typical student earns this raw score.

What is a serious limitation of using age equivalent of grade equivalents to describe a child’s performance?

AE scores compare children to the “average x-year-old.” However, the average x-year-old does not exist. Rather, the term average represents a range of performance for a particular age group. A third serious limitation of AE scores is the lack of information they provide about a test taker’s performance on a given test.

Why are standard scores often preferred to percentile scores?

Percentile ranks are preferred to standard scores for interpreting scores for individuals since you need to have some statistical expertise to interpret standard scores. Percentile ranks can usually simply explained in a few minutes without any statistical terms.

How old is 50 on PPVT III?

For example, the age equivalent for a raw score of 50 on the PPVT-III is** 4 years 0 months. ** The age equivalent for a raw score of 55 is 4 years 4 months. A change of 5 raw score points at this early age reflects a change of 4 months in terms of “age-equivalent” scores. However, the age equivalent for a raw score of 165 is 16 years 4 months, and for a raw score of 170 is 18 years 2 months. At the later age, a raw score change of 5 points results in almost 2 years’ difference in terms of “age-equivalent” scores.

Why are standard scores more accurate?
