| 4 | Number properties and operations | 0.97 | 0.01 |
| Measurement | 0.93 | 0.01 | |
| Geometry | 0.90 | # | |
| Data analysis, statistics, and probability | 0.88 | # | |
| Algebra | 0.93 | # | |

| # Rounds to zero. NOTE: In 2015, grade 12 was not assessed for state. Transformed scale scores below 0 were reset to values of 0, and any transformed scale scores greater than 300 (for grade 12) or 500 (for grades 4 and 8) were set to values of 300 or 500.
