NAEP Technical DocumentationCoefficients of linear transformations of the content-dimension subscales from the calibrating scale units to the units of the reporting scale, mathematics combined national and state assessment, by subscale and grade: 2013
Grade	Subscale	A	B
NOTE: In 2013, measurement and geometry were combined at grade 12. 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.
