NAEP Technical DocumentationCoefficients of linear transformations of the content-strand scales from the individual state calibrating scale units to the combined calibrating scale units, mathematics state assessment, by scale and grade: 2009

Grade	Scale	A	B
# Rounds to zero. 1 Measurement and Geometry were combined for grade twelve in 2009. NOTE: Transformed scale scores below 0 were reset to values of 0, and any transformed scale scores greater than 500 were set to values of 500.
