International comparisons provide reference points for researchers and policy analysts to understand trends and patterns in national education data and are important as U.S. students compete in an increasingly global economy.

Education at a Glance, an annual publication produced by the Organisation for Economic Co-operation and Development (OECD), provides data on the structure, finances, and progress of education systems in 36 OECD countries, including the United States, as well as a number of OECD partner countries. The report also includes state-level information on key benchmarks to inform state and local policies on global competitiveness. 

The recently released 2019 edition of the report shows that the United States is above the international average on some measures, such as participation in and funding of higher education, but lags behind in others, such as participation in early childhood education programs.

Distribution of 25- to 34-Year-Olds With a College Education, by Level of Education

The percentage of U.S. 25- to 34-year-olds with an associate’s or bachelor’s degree increased by 8 percentage points between 2008 and 2018, reaching 49 percent, compared with the OECD average of 44 percent. However, the attainment rates varied widely across the United States in 2017, from 32 percent for those living in Louisiana and West Virginia to 58 percent for those living in Massachusetts and 73 percent for those living in the District of Columbia.

The percentage of U.S. students completing a bachelor’s degree within 4 years was 38 percent in 2018, about the same as the average among OECD countries with available data (39 percent); however, after an additional 2 years, the U.S. graduation rate (69 percent) was slightly above the OECD average of 67 percent (achieved after 3 years). While a higher percentage of U.S. young adults had completed a bachelor’s degree compared with young adults in other OECD countries, a lower percentage had completed a master’s or doctoral degree. Eleven percent of 25- to 34-year-olds in the United States had completed a master’s or doctoral degree, compared with an average of 15 percent across OECD countries.

Higher Education Spending

U.S. spending on higher education is also relatively high compared with the OECD average, in both absolute and relative terms. The United States spent $30,165 per higher education student in 2017, the second-highest amount after Luxembourg and nearly double the OECD average ($15,556). Also, U.S. spending on higher education as a percentage of GDP (2.5 percent) was substantially higher than the OECD average (1.5 percent). These total expenditures include amounts received from governments, students, and all other sources. 

Early Childhood Education

Contrasting with enrollment patterns at the higher education level, the level of participation in early childhood education programs in the United States is below the OECD average and falling further behind. Between 2005 and 2017, average enrollment rates for 3- to 5-year-olds across OECD countries increased from 76 to 86 percent. In contrast, the rate in the United States remained stable at 66 percent during this time period. Among U.S. states, the 2017 enrollment rates for 3- to 5-year-olds ranged from less than 50 percent in Idaho, North Dakota, and Wyoming to more than 70 percent in Connecticut, the District of Columbia, and New Jersey.

Going deeper into the data, on average, 88 percent of 4-year-olds in OECD countries were enrolled in education programs in 2017, compared with 66 percent in the United States. The enrollment rate for 3-year-olds in the United States was 42 percent, compared with the OECD average of 77 percent.

Gender Gaps in Employment

Education at a Glance also looks at employment and other outcomes from education. The report found that the 2017 gender gap in employment rates was lower for those who had completed higher levels of education. This pattern holds in the United States, where the gender gap in the employment rate was particularly high among 25- to 34-year-olds who had not completed high school. For this age group, the employment rate was 73 percent for men and 41 percent for women, a difference of 32 percentage points, compared with the average difference of 28 percentage points across OECD countries. The gender gap in the employment rate was 14 percentage points among U.S. adults with only a high school education and 7 percentage points among those who had completed college.

In 2017, the gender differences in average earnings were also wider in the United States than in the OECD averages. These gender gaps in earnings between male and female full-time workers existed across all levels of education. In the United States, college-educated 25- to 64-year-old women earned 71 percent of what their male peers earned. This gender gap was wider than for all other OECD countries except for Chile, the Czech Republic, Hungary, Israel, Italy, Mexico, Poland, and the Slovak Republic.

This is just a sample of the information that can be found in Education at a Glance 2019. You can also find information on the working conditions of teachers, including time spent in the classroom and salary data; student/teacher ratios; college tuitions and loans; and education finance and per student expenditures. Education at a Glance also contains data on the international United Nations Sustainable Development Goals related to education.

Individuals are required to make a large number of financial decisions throughout the course of their lifetime, and financial literacy is an important skill for tasks ranging from setting a budget to saving money for retirement. A good foundation in financial literacy can help adolescents enter higher education and the workforce with a better understanding of how to make informed decisions.

The United States participated in the Program for International Student Assessment (PISA) financial literacy assessment in order to assess the financial literacy of a nationally representative sample of U.S. 15-year-olds. Students from 14 other education systems around the world also participated. Results are also available for Massachusetts and North Carolina. A recent NCES Data Point shows how U.S. students compare to their peers in other countries.

In 2015, The U.S. average score on the PISA financial literacy assessment was not measurably different from the average of the 10 participating Organization for Economic Cooperation and Development (OECD) countries. The U.S. average was lower than the average in six education systems, higher than the average in six, and not measurably different from the average in two education systems. The U.S. average score did not change measurably from 2012–the last time the assessment was conducted–to 2015.

As part of the PISA financial literacy assessment, students were tested on their knowledge and understanding of fundamental elements of the financial world, including financial concepts, products, and risks, and their ability to apply what they know to real-life situations involving financial issues and decisions. More information about the assessment, including sample questions, is available here.

Ten percent of U.S. 15-year-olds scored at the top proficiency level on financial literacy in 2015. Students reaching level 5 on the PISA assessment of financial literacy demonstrate that they can apply their understanding of a wide range of financial terms and concepts to contexts that may only become relevant to their lives in the long term.^[1] The percentage of students in the United States who scored at this level was lower than the OECD average and lower than the average in five education systems. It was higher than the average score in eight education systems and not measurably different from one country (Russian Federation).

The percentage of U.S. 15-year-old students scoring below level 2, which is considered a baseline level of proficiency by the OECD, was 22 percent.^[2] The U.S. percentage of low performers in 2015 was higher than four education systems and lower than five. The U.S. percentage did not differ significantly from that of the Netherlands, Australia, Poland, Italy, Spain, and the OECD average.

There was no measurable difference in the average financial literacy assessment scores for males and females in the United States in 2015. Females scored higher than males, on average, in five countries and lower than males in one country.

Indicators of School Crime and Safety provides a wealth of information on the safety of schools and colleges. The report is updated annually, which allows the public to compare many data points over time in the United States. But how does crime and safety for U.S. students compare to students from other countries? This year’s report helps put some of the U.S. data in an international context by comparing it to crime and safety indicators in other countries.

For example, 15 percent of U.S. fourth-grade students reported experiencing bullying at least once a month, which was lower than the international average (16 percent).^[1] This percentage was also lower than the percentages in 16 countries, higher than the percentages in 21 countries, and not measurably different from the percentages in 10 countries. Similarly, the percentage of U.S. eight-grade students who reported experiencing bullying at least once a week was lower than the international average (7 vs. 8 percent), and was lower than the percentages in 13 countries. The U.S. percentage was higher than the percentages in 16 countries, and not measurably different from the percentages in 6 countries.

Data from this spotlight come from the 2015 Trends in International Mathematics and Science Study (TIMSS). The primary purpose of TIMSS is to compare the mathematics and science performances of fourth- and eighth-grade students in participating countries and education systems. In addition to assessments, TIMSS provides questionnaires to students who participate, as well as to the teachers and principals of participating students. The 2015 TIMMS questionnaire collected data on students’ reports of bullying, teachers’ reports of whether the school environment is safe and orderly, and principals’ reports of school discipline issues for students in grades 4 and 8.

In the U.S., 7 percent of participating fourth-grade students attended schools that were less than safe and orderly, according to the data reported by their teachers.^[2] This was higher than the international average of 4 percent and higher than the percentages in 22 countries, while being not measurably different from the percentages in 19 countries. About 13 percent of participating U.S. eighth-grade students reported attending schools that were less than safe and orderly; higher than the international average of 8 percent and higher than the percentages in 26 countries.

About 3 percent of U.S. fourth-graders and 2 percent of U.S. eighth-graders attended schools with moderate to severe discipline problems, according to data reported by their principals.^[3] These percentages were lower than the international averages for fourth-graders and eighth-graders (10 percent and 11 percent, respectively).

In today’s increasingly global economy, there is a lot of interest in understanding how students in the United States (U.S.) are performing compared to their peers around the world. That is why the National Center for Education Statistics participates in and conducts several international assessments. One of those assessments—the Trends in International Mathematics and Science Study (TIMSS) Advanced—gives us a unique opportunity to see how our advanced students are performing in rigorous mathematics and physics classes as they complete high school. TIMSS Advanced is part of a broader data collection that also assesses the performance of 4th- and 8th-grade students in mathematics and science, the results of which are summarized in another blog entry.

The TIMSS Advanced 2015 was administered to students from nine education systems that were in their final year of secondary school who had taken or were taking advanced mathematics or physics courses. In the U.S., the TIMSS Advanced was given to over 5,500 students in Grade 12 who were taking or had taken advanced mathematics courses covering topics in geometry, algebra and calculus, or a second-year physics course. The last time that the U.S. participated in TIMSS Advanced was 1995.

What Percentage of Students Take Advanced Mathematics and Physics?

Among the nine education systems participating in TIMSS Advanced 2015, the percentage of the corresponding age cohort (18-year-olds in the U.S.) taking advanced mathematics varies widely. This percentage, which TIMSS calls the “coverage index,” ranges from a low of 1.9 percent to a high of 34.4 percent. The U.S. falls in the middle, with 11.4 percent of 18-year-olds taking advanced mathematics courses.  The U.S. advanced mathematics coverage index in 2015 has nearly doubled since 1995, when it was 6.4 percent.

In the U.S. and two other participating systems—Portugal and Russian Federation—the students taking advanced mathematics were split fairly evenly between male and female. In the remaining systems, the students in the coverage index were majority male, except for Slovenia, where 60 percent were female. Interestingly, Slovenia had the highest coverage index, at 34.4 percent.

It’s a different story in science for the U.S. Among 18-year-olds in the U.S., 4.8 percent took Physics, which was among the lowest for the nine systems participating in TIMSS Advanced. Only Lebanon (3.9 percent) had a lower percentage, while France had the highest coverage index at 21.5 percent. Males made up a majority of physics students in all nine participating systems, including the U.S. 

How Did U.S. Students Perform in Advanced Mathematics?

U.S. students scored 485 on TIMSS Advanced 2015 in advanced mathematics, which is not significantly different from the average U.S. score in 1995. It should be noted that on TIMSS 2015, given to a representative sample of fourth- and eighth-graders across the U.S., mathematics scores for both grades increased significantly from 1995 to 2015.

On TIMSS Advanced 2015 in advanced mathematics, two systems scored significantly higher than the U.S. (Lebanon and Russian Federation students who took intensive courses[1]) while five systems scored significantly lower (Norway, Sweden, France, Italy and Slovenia). The remaining two systems scored about the same as the U.S.

How Did U.S. Students Perform in Physics?

U.S. students scored 437 on TIMSS Advanced 2015 in physics, which was not statistically different than in 1995. No education system did better on physics in 2015 than 1995, but several did worse—four of the six systems that took the TIMSS Advanced in both 1995 and 2015 saw a significant drop in their scores.

Four of the nine countries participating in TIMSS Advanced 2015 in physics had a score that was significantly higher than the U.S. (Russian Federation, Portugal, Norway, and Slovenia) and three countries scored significantly lower than the U.S. (Lebanon, Italy and France). Sweden’s physics score was not significantly different than the U.S. 

A Note about Interpretation

It’s important to remember that there are differences in student characteristics and the structure of the various education systems that participated in TIMSS Advanced 2015. Those differences should be kept in mind when interpreting results. 

How do U.S. students compare to their international peers? A look at the Trends in International Mathematics and Science Study at 4th and 8th-grade

By Lydia Malley

In today’s interconnected world, it is important to understand the skills of students in the U.S. relative to their international peers. To this end, NCES participates in a number of international assessments. Results from one of these assessments, the Trends in International Mathematics and Science Study (TIMSS), were released on November 29th. Our new report, Highlights from TIMSS and TIMSS Advanced 2015, compares the mathematics and science performance of U.S. fourth- and eighth-grade to that of their peers in over 60 countries or education systems across 6 continents. This report also presents results from TIMSS Advanced, which assessed the advanced mathematics and physics knowledge and skills of twelfth-graders in 9 countries. The results from TIMSS Advanced are discussed more in depth in another blog post.

TIMSS results show that the mathematic scores of U.S. fourth- and eighth-grade students have improved over time, while science scores have held relatively steady. TIMSS is designed to measure trends in mathematics and science achievement. Conducted every 4 years, TIMSS 2015 represents the sixth such study since TIMSS was first conducted in 1995.

Among the report’s key findings:

Fourth-grade mathematics:

• Fourth-grade mathematics performance in the United States has improved since 1995.
• Among 54 education systems that participated in the most recent TIMSS, average scores in 10 systems were higher than the U.S. average, 9 education systems were not measurably different from the U.S. average, and average scores in 34 systems were lower than the U.S. average.

Eighth-grade mathematics:

• The eighth-grade average mathematics score of the United States in 2015 was higher than in any prior administration of TIMSS, since the first administration in 1995.
• Among 43 education systems, average scores in 8 systems were higher than the U.S. average, 10 education systems were not measurably different from the U.S. average, and average scores in 24 systems were lower than the U.S. average.

Fourth-grade science:

• Fourth-grade science performance in the United States in 2015 was not measurably different from the performance in 1995 or 2011.
• Among 53 education systems that participated in the 2015 TIMSS, average scores in 7 systems were higher than the U.S. average, 7 education systems were not measurably different from the U.S. average, and average scores in 38 systems were lower than the U.S. average.

Eighth-grade science: U.S. eighth-graders’ average science score increased between 1995 and 2015, although the scores in the most recent years (2011 and 2015) were not measurably different.

• Among 43 education systems, in 2015 average scores in 7 systems were higher than the U.S. average, in 9 education systems the average scores were not measurably different from the U.S. average, and average scores in 26 systems were lower than the U.S. average.

Results by Gender:

• Males scored 7 points higher than females in fourth-grade mathematics, and eighth-grade mathematics scores for males and females were not measurably different.
• Males scored four points higher than females in fourth-grade science and five points higher in eighth-grade science.

TIMSS is designed to align broadly with mathematics and science curricula in the participating education systems and, therefore, to reflect students’ school-based learning. TIMSS also collects information about educational contexts (such as students’ schools and teachers) that may be related to students’ achievement.

The full report is available at https://nces.ed.gov/timss/. In addition, TIMSS results are now easier than ever to access, with more than 60 tables and figures, reports, detailed descriptions of the assessments, technical notes and more available on the TIMSS 2015 website, at https://nces.ed.gov/timss/results15.asp.

TIMSS and TIMSS Advanced are sponsored by the International Association for the Evaluation of Educational Achievement (IEA) and managed in the United States by the National Center for Education Statistics (NCES), part of the U.S. Department of Education.
