answering a fouroption multiplechoice question, a 72 percent probability of correctly answering a fiveoption multiplechoice question, or a 71 percent probability of correctly answer
ing a sixoption multiplechoice question. For constructedresponse questions, the question description represents students’ performance rated as completely correct. Scores associated
with the three performance levels reported for age 13 are boxed. SOURCE: U.S. Department of Education, Institute of Education Sciences, National Center for Education Statistics, National Assessment of Educational Progress (NAEP),

Lower and middle performing 17yearolds made gains since the 1970s even though the overall
average mathematics score for this age group did not change significantly (figure 21). Scores
for students at the 10th, 25th, and 50th percentiles were higher in 2012 than in 1978.

As shown in the item map below, 17yearolds with a score of 286 were likely to be able to
add two fractions with like denominators. Students with a score of 320 were likely to be
able to successfully estimate an integer value for the square root of a number that is not
a perfect square. Seventeenyearolds with a score of 341 were likely to be able to analyze
a proportional relationship. Age 17 NAEP Mathematics Item Map
