Demystifying Age and Grade Equivalent Norms in Educational Assessments
When it comes to educational assessments, understanding the results can often feel overwhelming—especially when terms like "age equivalent" and "grade equivalent" norms are used. In a recent webinar, these concepts were discussed to offer insights for educators and school psychologists.
To Start: What Are Age and Grade Equivalent Norms?
Age and grade equivalent norms provide a way to compare assessment scores with the performance of other students at different ages or grade levels.
-
Age Equivalent (AE): This score reflects the average performance of individuals at a certain age. For example, if a 7-year-old student receives an age equivalent score of 9, it means their performance was similar to that of an average 9-year-old on the test.
-
Grade Equivalent (GE): Similarly, this score represents the typical performance of students at a certain grade level. If a 4th grader receives a grade equivalent of 6, it suggests their performance was comparable to that of an average 6th-grade student.
What do these scores actually mean?
While AE and GE scores offer a way to understand relative performance, they do not measure mastery of a specific grade level or predict future academic success. Instead, they provide a comparison to how a student performed relative to peers of different ages or grades.
A higher-than-expected GE score does not necessarily indicate readiness for more advanced coursework, and a lower GE score does not imply a lack of ability. These norms are best understood as part of a broader set of assessment data.
What do these scores actually mean?
To support accurate interpretation, keep these considerations in mind:
-
Context Matters: AE and GE scores are most meaningful when reviewed alongside standard scores, percentile ranks, and other assessment data.
-
Avoid Overgeneralization: A high AE or GE score does not mean a student should skip grades or be placed in advanced coursework without additional supporting information.
-
Clear Communication: When discussing results with parents, caregivers, or educators, it can be helpful to clarify what AE and GE scores indicate—and what they do not.
