Scaled Score vs Raw Score
公式
## How to Calculate a Scaled Score A scaled score converts a raw score to a standardized scale for fair comparison. ### Formula **Scaled Score = Scale Min + (Raw Score / Max Raw) x (Scale Max - Scale Min)** This linear mapping preserves relative performance across different test forms.
计算示例
A student gets a raw score of 45 out of 60, mapped to a 200–800 scale.
- 01Proportion = 45 / 60 = 0.75
- 02Scale range = 800 - 200 = 600
- 03Scaled score = round(200 + 0.75 x 600) = round(650) = 650
常见问题
Why are scores scaled?
Scaling allows fair comparison between students who take different versions of a test with varying difficulty levels.
Is a scaled score the same as a curve?
Not exactly. A curve adjusts scores based on class performance. Scaling uses a predetermined conversion to normalize scores.
Can I convert between SAT and ACT scores?
Yes, College Board provides concordance tables to convert between SAT and ACT scores, though it is not a simple linear conversion.
