What is considered the average standard score on most standardized tests?

The average standard score on most standardized tests is 100. This score is derived from a standard scoring system, where the mean is set at 100 with a standard deviation of 15. This design allows for comparison across different test-takers, as scores are normalized to reflect where an individual stands relative to the population. A score of 100 indicates that the individual is performing at the average level compared to the normative group, making it a crucial reference point in educational assessment and psychological evaluation.

In educational testing, a score of 100 also serves as a baseline for interpreting performance levels, guiding educators and professionals in understanding a student's abilities and needs. This context is fundamental for developing appropriate interventions or educational plans. When using other scores listed, such as 90, 75, or 50, they do not align with the commonly accepted standard for average performance across the majority of standardized assessments, which reinforces the prominence of the score of 100 as the average benchmark.
