NAEP Technical DocumentationCoefficients of linear transformations of the writing composite scale from the calibrating scale units to the units of the reporting scale, by grade: 2002

Grade	Scale	A	B
4	Composite	35.03	153.37
8	Composite	35.88	152.65
12	Composite	37.33	150.05
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 writing assessment uses a unidimensional scale.
