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.
What is an age based scale?
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.
How do you calculate equivalent grades?

Why is it better to use standard scores and percentile ranks than age and grade equivalents?
Standard scores are a more accurate representation of an examinee’s ability because they are based not only on the mean at a given age level but also on the distribution of scores. Standard scores also can be arithmetically compared and summarized.
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.
What are NCE scores?
NCE scores, or Normal Curve Equivalent scores, are a method of reporting test scores created for the US Department of Education. They range from 1-99 with a mean of 50, similar to percentiles. However, unlike percentiles, NCE scores maintain equal interval and can be meaningfully averaged and differenced.
How to determine age equivalent score?
The age equivalent score is determined by taking the mean test score of the group and using that as the point of comparison for each age group.
What is grade equivalent test?
Similar to age-equivalent tests are grade-equivalent tests, which are given to determine whether a student can handle the content that is meant for their grade level. Two children from different grade levels can have the same score. If your second grader has the same score as a third-grader, it doesn’t mean that your child can handle the third-grade curriculum.
What does it mean if your 8 year old has a 7 score?
If your 8-year-old child has a score of 7, it doesn’t mean that your child is underperforming. On the flip side, if your child’s score is 9, it doesn’t mean that they are smarter than the group. The test that your child took is designed for 8-year-old children, with test questions that are specific to their grade level, covering topics that have been discussed in their classes. If your child’s score is higher than their age level, do not assume that they could handle content for older children.
Is it normal for parents to get anxious about test scores?
It’s normal for parents to get anxious about test scores and ranking, especially when their child is still young. Do keep in mind that the age-equivalent test score is but one of the many tests that can provide a picture of your child’s mental ability. Always be mindful that the nature and validity of age-equivalent tests are up for debate in the first place. If you want to understand test scores and the types of tests that could better show your child’s abilities and potential, please consult professionals.

Definition
Age equivalent scores provide an estimate of the chronological age at which typically developing children demonstrate the skills exhibited by the child being assessed. The age equivalent score is based on the mean raw score on a test obtained by the group of children in the normative sample at a specific age.

How to determine the age equivalent of a student?
Determine the age equivalent for a student by comparing her score to the table. Based upon the previous example, if a student aged 6 years scored 43 on the test, then she would have an age equivalent of 7.3 years. This means that she has the knowledge of the average 7.3-year-old.
How to convert age to decimal?

What is the reliability of age and grade equivalents?
The reliability of age- and grade-equivalent scores is limited by the relationship between the equivalents and the raw scores on which they are based. An age or grade equivalent is simply the median raw score for a particular age or grade level.
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?
Standard scores are a more accurate representation of an examinee’s ability because they are based not only on the mean at a given age level but also on the distribution of scores. Standard scores also can be arithmetically compared and summarized. Age and grade equivalents are not a ratio or interval scale of measurement.
Can age and grade equivalents be added?
Age and grade equivalents are not a ratio or interval scale of measurement. They cannot be added, subtracted, or averaged.
