This objection also applies to several popular methods of standardizing raw test scores that fail to account sufficiently for differences in test items--methods like recentering and rescaling to convert scores to a bell-shaped curve, or converting to grade-level equivalents by comparing outcomes with the scores of same-grade students in a nationally representative sample. |
