NAEP Technical DocumentationCoefficients of Linear Transformation of the Subscales from the Individual State Calibrating Scale Units to the Combined State Calibrating Scale Units, Science State Assessment, by Grade: 2015
| Grade | A | B |
|---|---|---|
| 4 | 0.99 | # |
| 8 | 0.98 | 0.01 |
| # Rounds to zero. NOTE: In 2015, the grade 12 science assessment was national only. Transformed scale scores below 0 were reset to values of 0, and any transformed scale scores greater than 300 were set to values of 300.
