Mathematics -- Average Scale Score
  • Idaho fourth graders had an average scale score of 240 on the NAEP 2009 mathematics test. This was not significantly different from the average for fourth graders in the nation’s public schools (240).  
  • Idaho eighth graders had an average scale score of 287 on the NAEP 2009 mathematics test. Idaho's average was higher than the average for eighth graders in the nation’s public schools (283).
Mathematics -- Percent At or Above Basic
  • In 2011, 83 percent of Idaho fourth graders scored at or above NAEP Basic in mathematics. This was greater than their counterparts in the nation’s public schools (82 percent).
  • In 2011, 77 percent of Idaho eighth graders scored at or above NAEP Basic in mathematics.  This was greater than their counterparts in the nation’s public schools (72 percent). 
Mathematics Strands -- Average Scale Scores and Percentile Ranks

Strands -- Average Scale Scores

  • On NAEP 2011 mathematics, Idaho fourth graders scored higher than their national counterparts on the Measurement strand (242-238). Idaho fourth graders, however, were not significantly different from fourth graders in the nation's public schools in four strands: Properties & Operations (238-239), Geometry (240-241), Data Analysis & Statistics (242-242), and Algebra (243-244).
  • On NAEP 2011 mathematics, Idaho eighth graders scored higher than eighth graders in the nation's public schools in four strands: Properties & Operations (286-279), Measurement (285-278), Geometry (285-281), and Data Analysis & Statistics (287-285). They were not significantly different from their national counterparts in Algebra (289-288).

Strands -- Percentile Ranks

Note: No statistical significance is attached to "higher" when using or reporting percentile ranks.

  • On NAEP 2011 mathematics, the average fourth-grade student in Idaho scored higher than 48 percent of the fourth graders in the nation's public schools on Properties & Operations.
  • On NAEP 2011 mathematics, the average fourth-grade student in Idaho scored higher than 54 percent of the fourth graders in the nation's public schools on Measurement.
  • On NAEP 2011 mathematics, the average fourth-grade student in Idaho scored higher than 49 percent of the fourth graders in the nation's public schools on Geometry.
  • On NAEP 2011 mathematics, the average fourth-grade student in Idaho scored higher than 49 percent of the fourth graders in the nation's public schools on Data Analysis & Statistics.
  • On NAEP 2011 mathematics, the average fourth-grade student in Idaho scored higher than 48 percent of the fourth graders in the nation's public schools on Algebra.
  • On NAEP 2011 mathematics, the average eighth-grade student in Idaho scored higher than 57 percent of the eighth graders in the nation's public schools on Properties & Operations.
  • On NAEP 2011 mathematics, the average eighth-grade student in Idaho scored higher than 55 percent of the eighth graders in the nation's public schools on Measurement.
  • On NAEP 2011 mathematics, the average eighth-grade student in Idaho scored higher than 54 percent of the eighth graders in the nation's public schools on Geometry.
  • On NAEP 2011 mathematics, the average eighth-grade student in Idaho scored higher than 52 percent of the eighth graders in the nation's public schools on Data Analysis & Statistics.
  • On NAEP 2011 mathematics, the average eighth-grade student in Idaho scored higher than 51 percent of the eighth graders in the nation's public schools on Algebra.

Understanding NAEP Scores -- Exercise Caution!

The 2011 mathematics assessment of the National Assessment of Educational Progress (NAEP) used multiple-choice and constructed-response questions to examine student skills in number properties & operations, measurement, geometry, algebra & functions, and data analysis & probability.  Mathematics scores range from 0 to 500, where 214 is Basic (meets grade 4 expectations), 249 is Proficient (above grade level performance), and 282 is Advanced.

NAEP reports several different scores for each assessment, primarily achievement level scores (i.e., the percentage of students who score at or above a specified "cut-score") and scale scores.  While both of these scores report out one set off student knowledge and skills, it must be recognized that the different types of scores can and often do portray apparently different levels of student ability.

This statistical phenomenon is illustrated above by using different scores from NAEP 2011 to compare the mathematics achievement of Idaho fourth grade students with their peers in the other northwestern states:

[1] When we compare fourth-grade mathematics results from NAEP 2011 for Idaho and her neighbors using "percent at or above Basic," we find that two states scored higher than Idaho, two states scored lower than Idaho, and two states were not significantly different from Idaho.

[2] When we compare fourth grade mathematics results from NAEP 2011 for Idaho and her neighbors using the "average scale score," we find that four states scored higher than Idaho and that two states scored lower than Idaho.

The National Assessment Governing Board (NAGB) and the National Center for Education Statistics (NCES) believe that the achievement levels are useful for reporting trends in the educational achievement of students in the United States. However, based on the congressionally mandated evaluations so far, NCES agrees with the National Academy's recommendation that caution needs to be exercised in the use of the current achievement levels. Therefore, NCES concludes that these achievement levels should continue to be used on a trial basis and should continue to be interpreted and used with caution.
