Which scoring system ranges from 001 to 999 and is used to compare performance across populations?

1. Percentile Scores

2. Standard Scores

3. Scale Scores

4. Raw Scores

The correct answer is: Scale Scores

The scoring system that ranges from 001 to 999 and is typically used to compare performance across different populations is known as scale scores. Scale scores are constructed to allow for consistent comparison across assessments and populations, providing a means to interpret results meaningfully. Scale scores can adjust for variations in test difficulty and scoring so that they provide a uniform metric for comparison. The use of a range such as 001 to 999 allows for a continuum of performance levels, where scores can be situated in relation to each other and interpreted within the context of the entire population being assessed. In contrast, percentile scores represent the percentage of test-takers that a particular score is higher than, standard scores such as z-scores or T-scores are based on the mean and standard deviation of a set of scores, and raw scores are simply the number of items answered correctly without any adjustments for difficulty or population comparison. These other scoring methods do not provide the same standardized range and interpretive context that scale scores offer.
