NAEP Technical DocumentationCoefficients of linear transformations of the content-strand scales from the calibrating scale units to the units of the reporting scale, science combined national and state assessment, by scale and grade: 2011

Grade	Scale	A	B
NOTE: Any 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. In 2011, only grade 8 was assessed.
