Age Equivalent Test is a somewhat controversial measurement system that converts a raw test score into an age group for which the score represents an average achievement level. Thus, if the average score of 14-year-olds on a test of 100 questions is 70, any score of 70 would be recorded as 14, regardless of the age of the test taker. A 10-year-old or a 17-year-old scoring 70 would receive an age-equivalent score of 14 on the age-equivalent scale.
Age Equivalent Test Importance
The controversy surrounding such scales centers on possible misuse and misinterpretation especially in schools where tracking or ability grouping can determine a student’s academic future. Even a gifted student can score below average on an age-equivalent scale if, for whatever reason, he or she has not had access to the information required for the particular test. Similarly, a slower student with a specific fund of information might score higher than the appropriate age group on a specific battery of tests but not be able to function at that level on a sustainable basis.
