Long-Term Trend Reading and Mathematics Assessments. 2 THE NATION’S REPORT CARD I NTRODUCTION Introduction The National Assessment of Educational Progress (NAEP) longterm trend assessments provide the most extended retrospective
picture of student achievement in the United States. Results span
four decades of student performance by 9-, 13-, and 17-year-olds
in two major subject areas. Reading results are available for 12
assessments dating back to 1971, and mathematics results are
available for 11 assessments dating back to 1973.
There are two separate components of NAEP—long-term trend
assessments and main assessments. Results from the long-term
trend assessments are not directly comparable to those from the
main assessments because the long-term trend assessments use
different questions and because students are sampled by age
rather than by grade. Learn more about the differences between the
two NAEP assessments at http://nces.ed.gov/nationsreportcard/

Over the past four decades, the demographic makeup of American students has changed considerably.
Notably, Hispanic students now account for a larger proportion of students, and White students account
for a lower proportion, than in the 1970s. At age 13, for example, the proportion of Hispanic students more
than tripled between 1978 and 2012, while the proportion of White students decreased from 80 percent
to 56 percent (figure 1). These changes were similar at ages 9 and 17 (see appendix tables A-1 and A-2).
Another notable change is that students at all three ages tend to be in lower grades now than they were
in the past. For example, 72 percent of 13-year-olds were in 8th grade in 1978 compared with 60 percent
in 2012. The proportion of 13-year-olds in 7th grade or below has increased from 28 percent to 39 percent
over the same period. Similar patterns in grade enrollment were observed for 9- and 17-year-olds. P

Typical grade for age group. NOTE: Results for 1978 are from the original assessment format, and results for 2012 are from the revised assessment format. Black includes African American, Hispanic includes Latino, Pacific Islander includes Native Hawaiian, and “other” includes American Indian/Alaska Native, two or more races, and unclassified. Race categories exclude Hispanic origin. Detail may not sum to totals because of rounding. Accommodations and Exclusions in NAEP
NAEP aims to include all students sampled for the assessments including students with disabilities (SD)
and English language learners (ELL). This goal is accomplished by allowing many of the same accom
modations that students use on other tests such as extra testing time or individual admini...
