2015 Grade 12 Mathematics: The results are based on a nationally representative sample of 13,200 12th-graders from 740 schools. The mathematics assessment measures performance in four areas: (1) number properties and operations; (2) measurement and geometry; (3) data analysis, statistics and probability; and (4) algebra.
Students earning a score equivalent to the national average were likely to be able to use proportions to calculate height but were not likely to be able to use an algebra model to predict cost with a calculator. Some key highlights:
- 25 percent of grade 12 students across the country scored at or above the Proficient level, including 3 percent who scored at the Advanced level, in 2015.
- The percentage of students performing at or above the Basic level in 2015 was lower compared with data from 2013; however, a higher percentage of students performed below Basic.
- 47 percent of Asian students, 32 percent of white students and 31 percent of students of two or more races scored at or above the Proficient level; 7 percent of black, 10 percent of American Indian/Alaska Native and 12 percent of Hispanic students scored at or above Proficient in 2015.
- English language learners scored higher in 2015 than in 2013, but native English speakers scored lower.
- Students whose parents did not graduate from high school or had only some education after high school scored lower in 2015 than in 2013. There was no change in scores for students whose parents had graduated from high school or from college when compared with 2013.
- There was no change in scores for students with disabilities, and scores for students who are not identified as students with disabilities decreased compared with 2013.
2015 Grade 12 Reading: The results are based on a nationally representative sample of 18,700 12th-graders from 740 schools. The reading assessment measures students’ comprehension of two types of texts: literary and informational.
Students earning a score equivalent to the national average were likely to be able to make an inference based on details in a reading text but were not likely to be able to recognize detail related to the purpose of a reading text. Some key highlights:
- 37 percent of grade 12 students across the nation performed at or above the Proficient level, including 6 percent who scored at the Advanced level, in 2015.
- 49 percent of Asian students, 46 percent of white students and 45 percent of students of two or more races scored at or above Proficient, while 17 percent of black students, 25 percent of Hispanic students and 28 percent of American Indian/Alaska Native students reached that achievement level in 2015.
- The percentage of students performing below Basic in 2015 was higher compared with 2013.
- Since 2013, scores have increased for students performing at the 90th percentile and have declined for students at the 25th and 10th percentiles.
- The achievement gap between black and white students was wider when compared with the first assessment in 1992.
The National Assessment Governing Board, which sets policy for NAEP, began using NAEP in 2013 to estimate the percentage of grade 12 students who possess the knowledge and skills in reading and mathematics that would make them academically prepared for first-year college coursework. The Governing Board has been conducting extensive research in this area since 2008.
NAEP results are measured at three achievement levels: Basic, Proficient and Advanced. Basic denotes partial mastery of knowledge and skills, Proficient denotes solid academic performance and Advanced represents superior work.
To determine the percentage of students performing at or above the level indicating college preparedness, a single score is identified in each subject.
These scores correspond closely with scores that define the Proficient level but were independently determined as a result of the Governing Board’s preparedness research.
