Behind the degree: Direct measures of cognitive skills or reports of highest degree earned

By Heidi Silver-Pacuilla

Categories of educational attainment – or highest degree earned – are often used in social science research as an indicator of a person’s knowledge and skills. This measure is objective and readily available, easily understood by survey respondents as well as by consumers of research and survey data, strongly tied to policies (such as those promoting high school graduation and college completion rates), and widely used in the labor market by employers. Moreover, strong connections between educational attainment and positive life outcomes, such as employment, earnings, health, and civic engagement, are well established.

Yet, this measure is an imprecise indicator of the amount of knowledge and skills an individual acquired during the years of education it took to complete the degree. It also masks variation across individuals and programs of study. In addition, adults continue to acquire skills and knowledge from a variety of sources and activities over their lifetimes after completing a degree, while on the job or through employer-sponsored training, continuing education, family and household management, hobbies and interests, etc. Adults also lose fluency with skills that are not put to regular use.

The Program for the International Assessment of Adult Competencies (PIAAC) survey[i] provides direct measures of working-age adults’ cognitive skills based on their performance on literacy, numeracy, and problem-solving tasks set in real-life contexts. Performance is reported on a scale of 1-5 for literacy and numeracy and a scale of 1-3 for problem solving. It pairs these measures with a background questionnaire that asks about the use of skills at work and in daily life, work history, and other social, behavioral, and demographic indicators.

The direct measures of cognitive skills offer researchers the ability to study actual skills rather than only using attainment of a particular degree as a general indicator of skills, and to investigate how those assessed skills relate to behaviors and life outcomes. To illustrate how directly measured skills and educational attainment are not always aligned, we can compare direct performance to highest degrees earned. In the United States, of all adults who have attained only a high school degree, 20% performed in the lowest levels (Level 1 and Below Level 1) of literacy, while 7% of adults with an associate’s degree and 5% of those with a bachelor’s degree performed at this level. At the same time, the results showed that 6% of adults with no more than a high school diploma, 14% with only an associate’s degree, and 24% with a bachelor’s degree have very high literacy skills, at Level 4 or 5 on the same scale. See the full range of educational attainment and skill performance in literacy in the chart above.

Findings such as this can help inform policy, interventions, and communication strategies to better meet the needs of the recipients.

[i] The PIAAC survey is coordinated internationally by the OECD. NCES implements PIAAC in the United States. Results were first released in October 2013 with data from 23 countries. It is a household survey administered by trained data collectors to a nationally-representative sample of adults, ages 16 through 65, in each country, in the official language(s), and in most cases, in respondents’ homes on a laptop computer.

In the United States, the survey was first administered in 2012 and additional results, based on an expanded sample, will be released in 2015-2016. To learn more about the U.S. administration and reporting of the survey, as well as related data tools, see https://nces.ed.gov/surveys/piaac/.  

What is the Price of College?

By Lauren Musu-Gillette

For many students and their families, a college education is seen as an investment in the future. But like all investments, the initial sacrifices can seem burdensome and the future is uncertain. NCES seeks to help students and their families make good decisions by providing access to timely information about the price of college and the availability of financial aid. The NCES College Navigator web site provides an array of search tools to help students locate institutions that meet their financial needs and academic interests. Additionally, the Higher Education Opportunity Act of 2008 requires the U.S. Department of Education to report  current information and recent changes in net prices for college attendance, and tuition and fees charges at different types of institutions. Data on high and low cost institutions are published on the College Affordability and Transparency Center website. These sites can help students and their families make informed decisions about their most affordable options.

NCES recently released a report that examines the total, net, and out-of-pocket prices by type of institution in 2011-12. Although it is presented for institutions at an aggregate level, rather than for individual institutions, this report provides valuable information on the average prices for different types of degree-granting colleges, including breakdowns for students from families with different income levels. Overall, students at public 2-year colleges had the lowest average total price of attendance in 2011-12 at $15,000. Public 4-year institutions had the lowest average total price ($23,200) among 4-year colleges, and the average price of attendance at 4-year for-profit institutions was $29,300.  The average total price was highest at private non-profit 4-year institutions ($43,500); however, 4-year private nonprofit schools also awarded the most grant money and had the greatest percentage of students who received grants.

Factoring in financial aid, such as grants, loans, and work study, reduces the out-of-pocket costs that students and their families pay at various institutions. As a result, many full-time students pay less than the advertised total price of attendance. The out-of-pocket net price of attendance is based on the total price of attendance, but also accounts for the amount of grant and loan aid that students typically receive. Additionally, because many sources of aid are based on students’ financial need, there are differences in the out-of-pocket net price of attendance for dependent students from lower and higher income families. 

Overall, students at public 2-year colleges had the lowest out-of-pocket net price (after grants and loans) at $9,900 in 2011-12. The average out-of-pocket net price was $11,800 at public 4-year institutions and $15,000 at for-profit institutions. The largest difference between total price of attendance and out-of-pocket net price was at private nonprofit 4-year institutions, with the out-of-pocket net price ($18,100) being about $25,400 less than the average total price.  

Across all types of institutions, dependent students from lower income families (the lowest quarter of family incomes) had the lowest out-of-pocket net price. The average out-of-pocket net price for students from lower income families was $7,500 at public 2-year institutions, $7,100 at public 4-year institutions, $11,000 at private nonprofit institutions, and $15,000 at private for-profit institutions. In contrast, students from families in the top quarter of incomes had average out-of-pocket costs of $13,100 at public 2-year institutions, $16,800 at public 4-year institutions, $26,600 at private nonprofit institutions, and $22,300 at private for-profit institutions.

How variable are teachers' salaries?

By Lauren Musu-Gillette and Tom Snyder

Teachers play the primary role in the delivery of elementary and secondary instruction. About half of all public school staff were teachers and an additional 12 percent of staff were instructional aides in 2012. NCES collects a wide range of information related to teaching and teachers. One topic of high interest to current and potential teachers, as well as school officials, is the average salary for teachers. In fact, some of the most frequently visited tables on the Digest of Education Statistics webpage are those tables that present data on teachers’ salaries.

Data on teacher compensation and salaries are available from the Schools and Staffing Survey (SASS), collected by NCES. Salary data from this survey can be presented by teachers’ characteristics, such as sex, race/ethnicity, and years of full-time teaching experience. For example, in 2011-12 the average base salary for full-time teachers was $53,070. In addition, about 42 percent of full time teachers received supplemental pay for activities such as coaching, student activity sponsorship, or teaching evening classes, with an average value of $2,530. Some teachers had additional earnings from bonuses and summer employment.  

Teachers with more years of experience or higher levels of education received higher salaries on average. For teachers with one year or less of full-time teaching experience, the base salary for full-time teachers in 2011-12 was $40,540 compared to $64,820 for teachers with 30 or more years of experience. Data are also presented on base salary by highest degree earned. Teachers with a master’s degree and 30 to 34 years of experience had an average salary of $69,420 compared to an average of $58,510 for those teachers with a bachelor’s degree and the same amount of experience.  Overall, teachers with a bachelor’s degree or a master’s degree earned less in 2011-12 than in 1990-91, after adjusting for inflation. Average salaries are also available by state for teachers with a bachelor’s degree as their highest degree, or a master’s degree as their highest degree.

More recent information using estimated salaries show salary trends over a longer time period for teachers at both the state and national level in current and constant dollars. For example, the estimated average teacher salary at the national level in constant 2012-13 dollars was $39,329 in 1959-60, $57,152 in 1989-90, and $56,383 in 2012-13. 

My Brother’s Keeper: Using data to measure the educational progress of boys and young men of color

By Grace Kena

In February 2014, President Obama launched My Brother’s Keeper. This effort was designed to promote opportunity for and to unlock the full potential of the nation’s young people, including boys and young men of color, with help from government agencies, community leaders, private philanthropies, and businesses. As part of this initiative, federal agencies were asked to improve the accessibility of data that highlight both the challenges and the accomplishments of young people in progressing through the education system and entering the labor force. These statistics provide a composite view of recent trends for males and females across a variety of key dimensions.

Academic performance gaps in learning behaviors, knowledge, and skills, among children in various racial/ethnic groups are found as early as infancy,[1] preschool, and kindergarten[2]. In addition, children from lower-income families tend to have poorer educational outcomes than their peers from more well- off families, and relatively high percentages of males and females of color live in poverty. The latest data show that among 12th graders, the average reading and mathematics assessment scores for Black, Hispanic, and American Indian/Alaska Native 12th-graders were lower than the average scores for their peers. In addition, the percentage of Hispanic 18- to 24-year-olds who had not completed high school was higher than the average percentage. The percentages of Black, Hispanic, and American Indian/Alaska Native young men in this age group who were enrolled in college were also lower than the average, and the percentages of Black and Hispanic young men ages 25–29 who had earned a bachelor’s or higher degree were lower than the average for young men in this age group.

On the other hand, young people are making progress in education. For example, average mathematics scores increased between 2005 and 2013 for all male students as well as for Black and Hispanic students overall. The percentage of males ages 18–24 who had not completed high school decreased from 2000 to 2014 for most racial/ethnic groups, and the decreases for Black and Hispanic young men were among the largest. In addition, the percentages of Black and Hispanic young men in this age group who were enrolled in college increased from 2000 to 2013.

Educational attainment differences by students’ socioeconomic status

By Lauren Musu-Gillette

Obtaining higher education can be an important step towards better occupational and economic outcomes. Lower levels of educational attainment are associated with higher unemployment rates and lower earnings. Although an increasing number of students have enrolled in postsecondary institutions over the last several decades, there are still differences in the characteristics of students who complete various levels of postsecondary education.

One particularly important issue to explore is differences in educational attainment by socioeconomic status (SES) to investigate the opportunities for social mobility that education can provide. Recently, NCES published a spotlight indicator on this topic to be included in the annual Condition of Education report. The report uses data from the Education Longitudinal Study of 2002 (ELS:2002), which surveyed students at different points during their secondary and postsecondary years. Students were first surveyed in 2002 when they were sophomores in high school. Then, their highest level of education was assessed ten years later, in 2012.

Several key findings highlight differences in educational attainment by SES. For example:

  • Seven percent of low-SES students had not completed high school by 2012, greater than the percentages of middle- and high-SES students who had not completed high school by 2012;
  • By 2012, Fourteen percent of low-SES students who were high school sophomores in 2002 had earned a bachelor’s or higher degree, smaller than 29 percent of middle-SES students and 60 percent of high-SES students who earned a bachelor’s or higher degree; and
  • Compared to high-SES students, smaller percentages of low- and middle-SES students who performed in the highest quartile of math achievement during their sophomore year of high school went on to complete a bachelor’s degree by 2012.
