Financial literacy is a critical skill for young adults—especially as they begin to enter college or the workforce—that is often needed for partial or full financial independence and increased financial decision making.

The Program for International Student Assessment (PISA)—which is coordinated by the Organization for Economic Cooperation and Development (OECD)—gives us a unique opportunity to analyze and understand the financial literacy of 15-year-olds in the United States and other education systems around the world. PISA is the only large-scale nationally representative assessment that measures the financial literacy skills of 15-year-olds. The financial literacy domain was administered first in 2012 and then in 2015 and 2018. The 2018 financial literacy cycle assessed approximately 117,000 students, representing about 13.5 million 15-year-olds from 20 education systems. The fourth cycle began in fall 2022 in the United States and is currently being conducted.

How Frequently Do Students Discuss Financial Topics With Their Parents?

In 2018, all education systems that administered the PISA financial literacy assessment also asked students to complete a questionnaire about their experiences with money matters in school and outside of school. In the United States, about 3,500 students out of the total 3,740 U.S. PISA sample completed the questionnaire.

This blog post explores how frequently students reported talking about the following five topics with their parents (or guardians or relatives):

1. their spending decisions
2. their savings decisions
3. the family budget
4. money for things they want to buy
5. news related to economics or finance

Students’ answers were grouped into two categories: frequent (“a few times a month” or “once a week or more”) and infrequent (“never or almost never” or “a few times a year”).

We first looked at the degree to which students frequently discussed various financial topics with their parents. In 2018, the frequency of student-parent financial discussions varied by financial topic (figure 1):

• About one-quarter (24 percent) of U.S. 15-year-old students reported frequently discussing with their parents news related to economics or finance.
• More than half (53 percent) of U.S. 15-year-old students reported frequently discussing with their parents money for things they wanted to buy.

Do male and female students differ in how frequently they discuss financial topics with their parents?

In 2018, higher percentages of female students than of male students frequently discussed with their parents the family budget (35 vs. 32 percent) and money for things they wanted to buy (56 vs. 50 percent). Meanwhile, a lower percentage of female students than of male students frequently discussed with their parents news related to economics or finance (21 vs. 26 percent) (figure 2).

Are Students’ Financial Literacy Scores Related to How Frequently They Discuss Financial Matters With Their Parents?

With a scale from 0–1,000, the PISA financial literacy assessment measures students’ financial knowledge in four content areas:

1. money and transactions
2. planning and managing finances
3. risk and reward
4. the financial landscape

In 2018, the average score of 15-year-old students ranged from 388 points in Indonesia to 547 points in Estonia. The U.S. average (506 points) was higher than the average in 11 education systems, lower than the average in 4 education systems, and not measurably different from the average in 4 education systems. The U.S. average was also not measurably different from the OECD average.

We also examined the relationship between frequent parent–student financial discussions and students’ financial literacy achievement (figure 3). After taking into account students’ gender, race/ethnicity, immigration status, and socioeconomic status—as well as their school’s poverty and location—the results show that students who reported frequently discussing spending decisions with their parents scored 16 points higher on average than did students who reported infrequently discussing this topic. On the other hand, students who reported frequently discussing news related to economics or finance with their parents scored 18 points lower on average than did students who reported infrequently discussing this topic.  

Do Students Think That Young Adults Should Make Their Own Spending Decisions?

We also explored whether students agreed that young people should make their own spending decisions. In 2018, some 63 percent of U.S. 15-year-old students reported they agreed or strongly agreed, while 37 percent reported that they disagreed.

Do male and female students differ in their agreement that young adults should make their own spending decisions?

When comparing the percentage of male versus female students, we found that a lower percentage of female students than of male students agreed or strongly agreed that young people should make their own spending decisions (59 vs. 66 percent). This pattern held even after taking into account students’ gender, race/ethnicity, immigration status, and socioeconomic status as well as school poverty and location.  

Upcoming PISA Data Collections

A deeper understanding of the frequency of parent–student financial conversations, the types of topics discussed, and the relationships between financial topics and financial literacy could help parents and educators foster financial literacy across different student groups in the United States.

PISA began collecting data in 2022 after being postponed 1 year due to the COVID-19 pandemic; 83 education systems are expected to participate. The PISA 2022 Financial Literacy Assessment will include items from earlier years as well as new interactive items. The main PISA results will be released in December 2023, and the PISA financial literacy results will be released in spring/summer 2024.

Tracking differences between the performance of high- and low-performing students is one way of monitoring equity in education. These differences are referred to as achievement gaps or “score gaps,” and they may widen or narrow over time.

To provide the most up-to-date international data on this topic, NCES recently released Changes Between 2011 and 2019 in Achievement Gaps Between High- and Low-Performing Students in Mathematics and Science: International Results From TIMSS. This interactive web-based Stats in Brief uses data from the Trends in International Mathematics and Science Study (TIMSS) to explore changes between 2011 and 2019 in the score gaps between students at the 90th percentile (high performing) and the 10th percentile (low performing). The study—which examines data from 47 countries at grade 4, 36 countries at grade 8, and 29 countries at both grades—provides an important picture of prepandemic trends.

This Stats in Brief also provides new analyses of the patterns in score gap changes over the last decade. The focus on patterns sheds light on which part of the achievement distribution may be driving change, which is important for developing appropriate policy responses. 

Did score gaps change in the United States and other countries between 2011 and 2019?

In the United States, score gap changes consistently widened between 2011 and 2019 (figure 1). In fact, the United States was the only country (of 29) where the score gap between high- and low-performing students widened in both mathematics and science at both grade 4 and grade 8.

For any given grade and subject combination, no more than a quarter of participating countries had a score gap that widened, and no more than a third had a score gap that narrowed—further highlighting the uniqueness of the U.S. results.

Did score gaps change because of high-performing students, low-performing students, or both?

At grade 4, score gaps widened in the United States between 2011 and 2019 due to decreases in low-performing students’ scores, while high-performing students’ scores did not measurably change (figure 2). This was true for both mathematics and science and for most of the countries where score gaps also widened.

Low-performing U.S. students’ scores also dropped in both subjects at grade 8, but at this grade, they were accompanied by rises in high-performing students’ scores. This pattern—where the two ends of the distribution move in opposite directions—led to the United States’ relatively large changes in score gaps. Among the other countries with widening score gaps at grade 8, this pattern of divergence was not common in mathematics but was more common in science.

In contrast, in countries where the score gaps narrowed, low-performing students’ scores generally increased. In some cases, the scores of both low- and high-performing students increased, but the scores of low-performing students increased more.

Countries with narrowing score gaps typically also saw their average scores rise between 2011 and 2019, demonstrating improvements in both equity and achievement. This was almost never the case in countries where the scores of low-performing students dropped, highlighting the global importance of not letting this group of students fall behind.

In January 2022, NCES released the rescaled data files for three adult literacy assessments conducted several decades earlier: the 1992 National Adult Literacy Survey (NALS), the 1994 International Adult Literacy Survey (IALS), and the 2003 Adult Literacy and Lifeskills Survey (ALL). By connecting the rescaled data from these assessments with data from the current adult literacy assessment, the Program for the International Assessment of Adult Competencies (PIAAC), researchers can examine trends on adult skills in the United States going back to 1992. This blog post traces the history of each of these adult literacy assessments, describes the files and explains what “rescaling” means, and discusses how these files can be used in analyses in conjunction with the PIAAC files. The last section of the post offers several example analyses of the data.

A Brief History of International and National Adult Literacy Assessments Conducted in the United States

The rescaled data files highlighted in this blog post update and combine historical data from national and international adult literacy studies that have been conducted in the United States.

NALS was conducted in 1992 by NCES and assessed U.S. adults in households, as well as adults in prisons. IALS—developed by Statistics Canada and ETS in collaboration with 22 participating countries, including the United States—assessed adults in households and was administered in three waves between 1994 and 1998. ALL was administered in 11 countries, including the United States, and assessed adults in two waves between 2003 and 2008.

PIAAC seeks to ensure continuity with these previous surveys, but it also expands on their quality assurance standards, extends the definitions of literacy and numeracy, and provides more information about adults with low levels of literacy by assessing reading component skills. It also, for the first time, includes a problem-solving domain to emphasize the skills used in digital (originally called “technology-rich”) environments.

How Do the Released Data Files From the Earlier Studies of Adult Skills Relate to PIACC?

All three of the released restricted-use data files (for NALS, IALS, and ALL) relate to PIAAC, the latest adult skills assessment, in different ways.

The NALS data file contains literacy estimates and background characteristics of U.S. adults in households and in prisons in 1992. It is comparable to the PIAAC data files for 2012/14 and 2017 through rescaling of the assessment scores and matching of the background variables to those of PIAAC.

The IALS and ALL data files contain literacy (IALS and ALL) and numeracy (ALL) estimates and background characteristics of U.S. adults in 1994 (IALS) and 2003 (ALL). Similar to NALS, they are comparable to the PIAAC restricted-use data (2012/14) through rescaling of the literacy and numeracy assessment scores and matching of the background variables to those of PIAAC. These estimates are also comparable to the international estimates of skills of adults in several other countries, including in Canada, Hungary, Italy, Norway, the Netherlands, and New Zealand (see the recently released Data Point International Comparisons of Adult Literacy and Numeracy Skills Over Time). While the NCES datasets contain only the U.S. respondents, IALS and ALL are international studies, and the data from other participating countries can be requested from Statistics Canada (see the IALS Data Files/Publications and ALL Data pages for more detail). See the History of International and National Adult Literacy Assessments page for additional background on these studies. 

Table 1 provides an overview of the rescaled NALS, IALS, and ALL data files.

Table 1. Overview of the rescaled data files for the National Adult Literacy Survey (NALS), International Adult Literacy Survey (IALS), and Adult Literacy and Lifeskills Survey (ALL) 

What Does “Rescaled” Mean?

“Rescaling” the literacy (NALS, IALS, ALL) and numeracy (ALL) domains from these three previous studies means that the domains were put on the same scale as the PIAAC domains through the derivation of updated estimates of proficiency created using the same statistical models used to create the PIAAC skills proficiencies. Rescaling was possible because PIAAC administered a sufficient number of the same test questions used in NALS, IALS, and ALL.¹ These rescaled proficiency estimates allow for trend analysis of adult skills across the time points provided by each study.

What Can These Different Files Be Used For?

While mixing the national and international trend lines isn’t recommended, both sets of files have their own distinct advantages and purposes for analysis.

National files

The rescaled NALS 1992 files can be used for national trend analyses with the PIAAC national trend points in 2012/2014 and 2017. Some potential analytic uses of the NALS trend files are to

• Provide a picture of the skills of adults only in the United States;
• Examine the skills of adults in prison and compare their skills with those of adults in households over time, given that NALS and PIAAC include prison studies conducted in 1992 and 2014, respectively;
• Conduct analyses on subgroups of the population (such as those ages 16–24 or those with less than a high school education) because the larger sample size of NALS allows for more detailed breakdowns along with the U.S. PIAAC sample;
• Focus on the subgroup of older adults (ages 66–74), given that NALS sampled adults over the age of 65, similar to PIAAC, which sampled adult ages 16–74; and
• Analyze U.S.-specific background questions (such as those on race/ethnicity or health-related practices).

International files

The rescaled IALS 1994 and ALL 2003 files can be used for international trend analyses among six countries with the U.S. PIAAC international trend point in 2012/2014: Canada, Hungary, Italy, Norway, the Netherlands, and New Zealand. Some potential analytic uses of the IALS and ALL trend files are to

• Compare literacy proficiency results internationally and over time using the results from IALS, ALL, and PIAAC; and
• Compare numeracy proficiency results internationally and over time using the results from ALL and PIAAC.

Example Analyses Using the U.S. Trend Data on Adult Literacy

Below are examples of a national trend analysis and an international trend analysis conducted using the rescaled NALS, IALS, and ALL data in conjunction with the PIAAC data.

National trend estimates

The literacy scores of U.S. adults increased from 269 in NALS 1992 to 272 in PIAAC 2012/2014. However, the PIAAC 2017 score of 270 was not significantly different from the 1992 or 2012/2014 scores.

On June 8 and 9, the Institute of Education Sciences (IES) and the Council of the Great City Schools (CGCS) will host a Reading Summit to address one of the most important issues confronting American education today: the declining reading performance of America’s lowest-performing students and the growing gap between low- and high-performing students.

At this 2-day virtual event, participants will explore the results of the National Assessment of Educational Progress (NAEP), as well as other IES data, and learn strategies to help educators and low-performing readers make progress.

Learn more about the summit’s agenda and speakers—including IES Director Mark Schneider, NCES Commissioner James L. Woodworth, and NCES Associate Commissioner Peggy Carr—and register to participate (registration is free).

In the meantime, explore some of the data NCES collects on K–12 literacy and reading achievement, which show that the scores of students in the lowest-performing groups are decreasing over time.

• The National Assessment of Educational Progress (NAEP) administers reading assessments to 4th-, 8th-, and 12th-grade students. The most recent results from 2019 show that average reading scores for students in the 10th percentile (i.e., the lowest-performing students) decreased between 2017 and 2019 at grade 4 (from 171 to 168) and grade 8 (from 219 to 213) and decreased between 2019 and 2015 at grade 12 (from 233 to 228).

• The Progress in International Reading Literacy Study (PIRLS) is an international comparative assessment that measures 4th-grade students’ reading knowledge and skills. The most recent findings from 2016 show that the overall U.S. average score (549) was higher than the PIRLS scale centerpoint (500), but at the 25th percentile, U.S. 4th-graders scored lower in 2016 (501) than in 2011 (510).

• The Program for International Student Assessment (PISA) is a study of 15-year-old students’ performance in several subjects, including reading literacy. The 2018 results show that, although the overall U.S. average reading score (505) was higher than the OECD average score (487), at the 10th percentile, the U.S. average score in 2018 (361) was not measurably different from the score in 2015 and was lower than the score in 2012 (378).

NCES also collects data on young children’s literacy knowledge and activities as well as the literacy competencies of adults. Here are a few data collections and tools for you to explore:

• The National Household Education Surveys (NHES) program collects data on young children’s home literacy activities with family members. See the section below for more on these data. 

• The International Early Learning Study (IELS) is an international play-based assessment of 5-year-olds’ knowledge and skills in four key areas, including emergent literacy. Learn about the 2018 pilot study.

• The Program for the International Assessment of Adult Competencies (PIAAC) assesses the skills of adults across the world in various domains, including literacy.

This year, the Condition of Education includes a newly updated indicator on literacy activities that parents reported doing with young children at home. Here are some key findings from this indicator, which features data from the 2019 NHES Early Childhood Program Participation Survey:

In the week before the parents were surveyed,

• 85 percent of 3- to 5-year-olds were read to by a family member three or more times.

• 87 percent of 3- to 5-year-olds were told a story by a family member at least once.

• 96 percent of 3- to 5-year-olds were taught letters, words, or numbers by a family member at least once.

In the month before the parents were surveyed,

• 37 percent of 3- to 5-year-olds visited a library with a family member at least once.

Be sure to read the full indicator in the 2021 Condition of Education, which was released in May, for more data on young children’s literacy activities, including analyses by race/ethnicity, mother’s educational attainment, and family income.

NCES recently released results from the 2019 Trends in International Mathematics and Science Study (TIMSS). TIMSS tests students in grades 4 and 8 in mathematics and science every 4 years. The results show that

• Across both subjects and grades, the United States scored, on average, in the top quarter of the education systems that took part in TIMSS 2019.
  • Among the 64 education systems that participated at grade 4, the United States ranked 15th and 8th in average mathematics and science scores, respectively.
  • Among the 46 education systems that participated at grade 8, the United States ranked 11th in average scores for both subjects.
• On average, U.S. scores did not change significantly between the 2011 and 2019 rounds of TIMSS.

Average scores are one measure of achievement in national and international studies. However, they provide a very narrow perspective on student performance. One way to look more broadly is to examine differences in scores (or “score gaps”) between high-performing students and low-performing students. Score gaps between high performers and low performers can be one indication of equity within an education system. Here, high performers are those who scored in the 90th percentile (or top 10 percent) within their education system, and low performers are those who scored in the 10th percentile (or bottom 10 percent) within their education system.

In 2019, while some education systems had a higher average TIMSS score than the United States, none of these education systems had a wider score gap between their high and low performers than the United States. This was true across both subjects and grades.

Figure 1 shows an example of these findings using the grade 8 mathematics data. The figure shows that 17 education systems had average scores that were higher or not statistically different from the U.S. average score.

• Of these 17 education systems, 13 had smaller score gaps between their high and low performers than the United States. The score gaps in 4 education systems (Singapore, Chinese Taipei, the Republic of Korea, and Israel) were not statistically different from the score gap in the United States.
• The score gaps between the high and low performers in these 17 education systems ranged from 170 points in Quebec, Canada, to 259 points in Israel. The U.S. score gap was 256 points.
• If you are interested in the range in the score gaps for all 46 education systems in the TIMSS 2019 grade 8 mathematics assessment, see Figure M2b of the TIMSS 2019 U.S. Highlights Web Report, released in December 2020. This report also includes these results for grade 8 science and both subjects at the grade 4 level.

NOTE: This figure presents only those education systems whose average scores were similar to or higher than the U.S. average score. Scores are reported on a scale of 0 to 1,000 with a TIMSS centerpoint of 500 and standard deviation of 100.

From 2011 to 2019, U.S. average scores did not change significantly. However, the scores of low performers decreased, and score gaps between low and high performers grew wider in both subjects and grades. In addition, at grade 8, there was an increase in the scores of high performers in mathematics and science over the same period. These two changes contributed to the widening gaps at grade 8.

Figure 2 shows these results for the U.S. grade 8 mathematics data. Average scores in 2011 and 2019 were not significantly different. However, the score of high performers increased from 607 to 642 points between 2011 and 2019, while the score of low performers decreased from 409 to 385 points. As a result, the score gap widened from 198 to 256 points between 2011 and 2019. In addition, the 2019 score gap for grade 8 mathematics is significantly wider than the gaps for all previous administrations of TIMSS.

These TIMSS findings provide insights regarding equity within the U.S. and other education systems. Similar results from the National Assessment of Educational Progress (NAEP) show that mathematics scores at both grades 4 and 8 decreased or did not change significantly between 2009 and 2019 for lower performing students, while scores increased for higher performing students. More national and international research on the gap between high- and low-performing students could help inform important education policy decisions that aim to address these growing performance gaps.
