Scaled Scores
Captions available
The idea
A scaled score converts a raw score, the number correct, onto a reporting scale that means the same across test forms.
In practice
On CLEP exams, each correct answer earns one point, wrong or skipped answers lose nothing, and a scaled score of 50 is equivalent to a course grade of C.
Where people slip
Measurement error can be restated in scale-score units.
