The National Center for Education Statistics (NCES) conducts some of the most complex education surveys in the world, and we work hard to make these surveys as effective and efficient as possible. One way we make sure our surveys are successful is by conducting multiple tests before we fully launch a national data collection.

Even prior to a field test, NCES develops survey materials and procedures using much smaller-scale cognitive laboratory testing and focus-group processes. These initial development procedures help ensure that materials are clear and procedures are understood before we conduct field testing with larger and more representative groups of respondents. Then, we launch the field tests to test data-collection operations and survey processes and procedures. Field tests are small-scale surveys that include a range of respondents and are designed to test the survey questionnaires and survey administration procedures in a real-world situation prior to the launch of a major study. The field test results allow us to make any necessary adjustments before starting the national data collection. Field tests also allow us to test specific survey items and ensure that they are valid and reliable. Without a field test, we could risk spending the public’s time and money on large data-collection efforts that do not produce the intended information.

NCES is about to begin the Early Childhood Longitudinal Study, Kindergarten Class of 2022–23 (ECLS-K:2023) with a field test early this year. The ECLS-K:2023 will focus on children’s early school experiences, beginning with preschool and continuing through fifth grade. From the spring of 2022 through the spring of 2028, we will collect national study data from children and their parents, teachers, and school administrators to answer questions about children’s early learning and development, transition into kindergarten and beyond, and experiences in the elementary grades. 

Although the ECLS-K:2023 will be similar in many ways to prior ECLS kindergarten studies, we are adding a round of data collection prior to the children’s kindergarten year—the national spring 2022 preschool round. For this preschool survey, we’ll send an invitation to participate to a sample of residential addresses within selected areas of the United States. Potential participants will first be asked to fill out a brief screener questionnaire. If they report that an ECLS-eligible child is in the household, they will be asked additional important questions about early childhood topics, such as their child’s literacy, language, math, and social skills; activities done with the child in the home (e.g., singing songs, playing games, reading); and characteristics of any early care and education (i.e., child care) arrangements for the child.   

Because the ECLS-K:2023 preschool data need to be comprehensive and reliable so that they can inform public discussions and policies related to early elementary education, it’s crucial that we test our procedures and questions for this new preschool round by conducting a field test in early 2020.  

If you receive a letter about participating in the 2020 ECLS field test, you’re being selected to represent thousands of households like yours and provide NCES with the data we need to make decisions about how to best conduct the ECLS-K:2023. The participation of all the selected households who receive our mailings, even those without children, is essential for a successful field test and, ultimately, a successful ECLS-K:2023.

If you are selected for the ECLS field test and have any questions about participating, please visit the participant information page.

When it comes to choosing a child care arrangement, cost is a big factor in the choices parents make, according to recently released data from the National Center for Education Statistics (NCES).

Every 3 years, NCES conducts the Early Childhood Program Participation (ECPP) component of the National Household Education Surveys Program (NHES) to answer questions about young children’s care and education before starting kindergarten. The ECPP survey reported that 60 percent of children under age 5 who were not yet in kindergarten participated in at least one weekly nonparental care arrangement in 2016. Of those receiving nonparental care,

• 42 percent received only center-based care;

• 25 percent received only relative care;

• 20 percent received multiple types of care; and

• 12 percent received only nonrelative care.

When asked what factors influenced their choice of child care arrangements, 51 percent of parents ranked the cost as “very important” when selecting an arrangement in 2016. This percentage was higher among parents of children in relative care (63 percent) than among parents of children in multiple types of care arrangements (50 percent) and parents of children only in center-based care (47 percent).

Overall, in 2016, some 39 percent of parents with children in nonparental care reported that they had difficulty finding child care. This rate was lowest for parents of children only in relative care (23 percent) and highest for parents of children only in nonrelative care (53 percent). However, among parents who had difficulty trying to find child care, cost was a larger concern for those with children only in relative care than it was for those with children in other arrangements (see figure 1).

In 2016, fees were less common and costs were generally lower for parents with children in relative care than for parents with children in other types of nonparental care arrangements. Thirty-two percent of parents with children in at least one care arrangement were not charged fees for care, and 58 percent of those children were in relative care. Among children in relative care, 80 percent were cared for by grandparents. When parents paid grandparents for their children’s care, they paid an average of $4.86 per hour, less than the average across all types of care arrangements ($6.93 per hour).

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.

We are pleased to present The Condition of Education 2018, a congressionally mandated annual report summarizing the latest data on education in the United States. This report is designed to help policymakers and the public monitor educational progress. This year’s report includes 47 indicators on topics ranging from prekindergarten through postsecondary education, as well as labor force outcomes and international comparisons. 

In addition to the regularly updated annual indicators, this year’s spotlight indicators highlight new findings from recent NCES surveys. The first spotlight indicator examines the choices and costs that families face as they select early childhood care arrangements. Drawing on data from the NCES National Household Education Survey, the indicator finds that early childhood care expenses were higher in 2016 than in 2001. For example, families’ average hourly out-of-pocket expenses for center-based care were 72 percent higher in 2016 ($7.60) than in 2001 ($4.42), in constant 2016–17 dollars. The indicator also finds that in 2016, some 57 percent of children under the age of 6 had parents who reported there were good choices for child care where they lived. Among children whose parents reported difficulty finding child care in 2016, some 32 percent cited cost as the primary reason. The complete indicator, Early Childhood Care Arrangements: Choices and Costs, contains more information about how these findings varied by family income, race/ethnicity, locale (urban, suburban, town, or rural), and children’s age.

Average hourly out-of-pocket child care expense for children under 6 years old and not yet in kindergarten whose families paid for child care, by primary type of child care arrangement: 2001 and 2016

¹ Center-based arrangements include day care centers, Head Start programs, preschools, prekindergartens, and childhood programs.
NOTE: Estimates include only those children whose families paid at least part of the cost out of pocket for their child to receive nonparental care at least weekly.

The second spotlight describes the characteristics of teachers who entered the teaching profession through an alternative route to certification program. Compared to those who entered through a traditional route, higher percentages of alternative route teachers in 2015–16 were Black (13 vs. 5 percent), Hispanic (15 vs. 8 percent), of Two or more races (2 vs. 1 percent), and male (32 vs. 22 percent), and lower percentages were White (66 vs. 83 percent). Overall, 18 percent of public school teachers in 2015–16 had entered teaching through an alternative route to certification program. The percentages were higher among those who taught career or technical education (37 percent), natural sciences (28 percent), foreign languages (26 percent), English as a second language (24 percent), math and computer science (22 percent), and special education (20 percent). The analysis also examines how the prevalence of alternative route teachers varies between charter schools and traditional public schools, between high and low poverty schools, and between schools that enroll high or low percentages of racial/ethnic minority students. For more findings from this analysis of data from the National Teacher and Principal Survey, see the complete indicator, Characteristics of Public School Teachers Who Completed Alternative Route to Certification Programs.

Percentage distribution of public elementary and secondary school teachers, by route to certification and race/ethnicity: 2015–16

NOTE: Teachers were asked whether they entered teaching through an alternative route to certification program, which is a program that was designed to expedite the transition of nonteachers to a teaching career (for example, a state, district, or university alternative route to certification program). Detail may not sum to totals because of rounding. Race categories exclude persons of Hispanic ethnicity. Data for American Indian/Alaska Native teachers who entered teaching through a traditional route and Pacific Islander teachers who entered teaching through traditional and alternative routes round to zero and are not displayed.

The third spotlight presents data on average student loan balances for students completing graduate degrees. Using data from the National Postsecondary Student Aid Study, this indicator examines how average student loan balances changed between 1999–2000 and 2015–16, and how those trends varied by degree type. Among graduate school completers who had student loans for undergraduate or graduate studies, average student loan balances increased for all degree types (in constant 2016–17 dollars). For example, average student loan balances for students who completed research doctorate degrees, such as a Ph.D., doubled during this time period, from $53,500 to $108,400 (an increase of 103 percent). Average student loan balances increased by 90 percent for those who completed professional doctorate degrees, such as medical doctorates and law degrees (from $98,200 to $186,600). The complete indicator, Trends in Student Loan Debt for Graduate School Completers, also describes how average student loan balances varied among specific degree programs, such as medical doctorates, law degrees, and master’s degrees in business administration.

Average cumulative student loan balance for graduate school completers, by degree type: Selected years, 1999–2000 through 2015–16

¹ Includes chiropractic, dentistry, law, medicine, optometry, pharmacy, podiatry, and veterinary medicine. 
NOTE: Data refer to students who completed graduate degrees in the academic years indicated. Includes student loans for undergraduate and graduate studies. Average excludes students with no student loans.

In 2014–15, boys had higher fourth-grade math scores than girls, but no significant differences were found in boys’ versus girls’ fourth-grade reading knowledge and skills. These findings come from the most recent data release for the Early Childhood Longitudinal Study, Kindergarten Class of 2010–11 (ECLS-K:2011). A recently released report provides a first look at the status of students who were in kindergarten for the first time during the 2010-11 school year and were in fourth grade in 2014-15. The longitudinal nature of this study allows for a comparison of trends over time. For example, differences in math scores between boys and girls were also observed in third grade but not in earlier grades. No significant differences in reading results for boys and girls have been detected in any grade between kindergarten and fourth. More data on assessment scores, as well as the demographic and family characteristics of the cohort of students who were first-time kindergartners in 2010-11, are available in the reports.

The series of Early Childhood Longitudinal Studies are consistently some of the most popular NCES studies due in large part to the fact that they provide comprehensive and reliable data on important topics such as child development, school readiness, and early school experiences. The ECLS-K:2011 was designed to provide data that can be used to describe and to better understand children’s development and experiences in the elementary grades, and how children’s early experiences relate to their later development, learning, and experiences in school. The study is longitudinal, meaning that it followed the same group of children over time; in the case of the ECLS-K:2011, children were followed from their kindergarten year (the 2010-11 school year) until the spring of 2016, when most of the children were in the fifth grade.

All planned waves of data through fifth grade have been collected and staff at the National Center for Education Statistics (NCES) are hard at work releasing reports of the findings as well as the data from all rounds of the study. Researchers, educators, policy makers, and other interested members of the public now have access to much of the important data from the ECLS-K:2011, with additional reports and data releases on their way.

The diverse sample of children who participated in the ECLS-K:2011 is nationally representative of students who were in kindergarten in U.S. schools in the 2010-11 school year. Information on children’s cognitive, social, emotional, and physical development was collected every year using direct child assessments and surveys for the adults central to the children’s education. Adults surveyed for the study included the children’s parents/guardians, their teachers, their school administrators, and their kindergarten before- and after-school care providers. Topics covered by the surveys included the children’s home environment, home educational activities, school environment, classroom environment, classroom curriculum, teacher qualifications, and before- and after-school care. 

Public-use data from the kindergarten through fourth-grade rounds of the ECLS-K:2011 are now available online. A restricted-use dataset with data from the kindergarten through fourth-grade rounds is also available to qualified researchers with an IES Restricted-use Data License. For information on licensing, please see https://nces.ed.gov/pubsearch/licenses.asp. The schedule of future data releases is available on the ECLS website.
