Average Scale Score
  • Idaho fourth graders had an average scale score (241) on the NAEP 2009 mathematics test that was higher than the national average (239).
  • Idaho eighth graders had an average scale score (287) on the NAEP 2009 mathematics test that was higher than the national average (282).
Percent At or Above Basic

Note: Grade Level Expectations = NAEP Basic = ISAT Proficient.

  • In 2009, 85 percent of Idaho fourth graders scored at or above NAEP Basic in mathematics, which was higher than their peers nationwide (81 percent). [Similarly, 85 percent of Idaho fourth graders, in 2009, scored at or above ISAT proficient, i.e.., 86 percent at or above grade level expectations.]
  • In 2009, 78 percent of Idaho eighth graders scored at or above NAEP Basic in mathematics, which was higher than their peers nationwide (71 percent). [Similarly, 78 percent of Idaho eighth graders, in 2009, scores at or above ISAT proficient, i.e., 78 percent at or above grade level expectations.]

  • Idaho fourth graders, in 2009, scored higher than the national average on Total Mathematics and on one strand (Measurement), but was not statistically different from the national average in four strands (Numbers and Operations, Geometry, Algebra and Functions, and Data Analysis & Statistics).
  • Idaho eighth graders, in 2009, scored higher than the national average on Total Mathematics and higher than the national average on all five mathematics strands (Numbers and Operations, Measurement, Geometry, Algebra and Functions, and Data Analysis & Statistics).

Noteworthy Accomplishments in Grade 8 Mathematics

Idaho was one of only 14 states that enjoyed a significant increase from 2007 to 2009 in eighth grade NAEP average scores. In addition, the graph below supports these statements about eighth grade achievement mathematics achievement in 2009:

  • Idaho has seen a continuing reduction from 1990 to 2009 in the percentage of eighth grade students who score below grade level expectations (i.e., below NAEP Basic) in mathematics, from 37 percent down to 22 percent.
  • The drop from 25 percent of Idaho eighth graders scoring below grade level in 2007 to 22 percent in 2009 was statistically significant.
  • The increase from 6 percent of Idaho eight graders scoring NAEP Advanced (i.e., TAG level performance) in 2007 to 8 percent in 2009 was statistically significant.
  • On the eighth grade mathematics assessment in 2009, Idaho had significantly fewer students (22 percent) scoring below NAEP Basic than the nation (29 percent), and significantly more students (30 percent) scoring NAEP Proficient than the nation (25 percent)
