NAEP Technical DocumentationCoefficients of linear transformations of the mathematics scales from the calibrating scale units to the units of the reporting scale, by grade: 2003

Grade	Scale	A	B
4	Number sense, properties, and operations	31.34	232.61
	Measurement	32.24	234.91
	Geometry and spatial sense	24.96	233.98
	Data analysis, statistics, and probability	27.67	237.52
	Algebra and functions	27.46	240.03
8	Number sense, properties, and operations	37.73	277.16
	Measurement	46.88	275.76
	Geometry and spatial sense	33.09	274.70
	Data analysis, statistics, and probability	40.02	280.65
	Algebra and functions	36.39	280.30
NOTE: Mathematics was not assessed at grade 12 in 2003. Any 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.
