NAEP Technical DocumentationCoefficients of linear transformations of the civics scale from the calibrating scale units to the units of the reporting scale, civics assessment, by grade: 2006

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. The NAEP civics assessment uses a unidimensional scale.
