New Data Tell the Story of Public and Private Schools and Their Leaders

Which schools would you guess, on average, spend more instructional time on English, reading, and language arts—public schools or private schools? How about on mathematics?

These questions and many others are answered in recently released reports on U.S. public and private schools and principals. The data in these reports are from the 2017–18 National Teacher and Principal Survey (NTPS), which is administered by the National Center for Education Statistics (NCES). NTPS previously collected data from public schools, principals, and teachers during the 2015–16 school year, but this is the first private school collection since the 2011–12 school year. (The latest NTPS data on public and private school teachers will be released later this year.)

The NTPS collects data about principals’ educational backgrounds and goals, as well as the climate of their schools and other general information about their schools and special programs and services provided. These data serve as a resource for researchers, policymakers, and the general public who are interested in understanding the current experiences and conditions of U.S. public and private schools.

The 2017–18 NTPS featured several new topic areas, such as the following:

  • School instruction time. Overall, schools reported that third-graders spent a weekly average of 500 minutes on instruction in English, reading, and language arts; 350 minutes on instruction in arithmetic or mathematics; and 170 minutes each on instruction in science and social studies or history. Here are some data to answer the questions from the beginning of this post:
    • Public schools reported that third-graders spent a weekly average of 540 minutes on instruction in English, reading, and language arts; 370 minutes on instruction in arithmetic or mathematics; 170 minutes on instruction in science; and 160 minutes on instruction in social studies or history.
    • Private schools reported that third-graders spent a weekly average of 400 minutes on instruction in English, reading, and language arts; 280 minutes on instruction in arithmetic or mathematics; and 170 minutes each on instruction in science and social studies or history.

  • ​Principals’ professional development. Overall, 83 percent of all principals reported participating in any professional development activities in the 2016–17 school year. Specifically, 85 percent of public school principals and 77 percent of private school principals reported doing so.
  • Evaluation of principals. Among public school principals, relatively more principals in traditional public schools were evaluated during the last school year than were principals in public charter schools (79 and 69 percent, respectively). Relatively more private school principals in Catholic and nonsectarian schools (63 and 58 percent, respectively) were evaluated during the last school year than were principals in other religious schools (41 percent).

Data files for the 2017–18 school and principal questionnaires will be released later this year. In order to protect the identities of responding schools and principals, researchers must apply for a restricted-use license to access the full restricted-use data files. Data will also be available through NCES’ online data tool, DataLab, where users can create custom tables and regressions without a restricted-use license.

Celebrating School Library Month: A Look at Library Media Centers

 

April is School Library Month, which recognizes the important role that school librarians and libraries play in K-12 education. More than 90 percent of public elementary and secondary schools have a library media center, according to the National Teacher and Principal Survey (NTPS), which collects data about school librarians and libraries. In honor of School Library Month, here are some facts and figures from the NTPS.

 

Library staff

  • Public schools employed approximately 56,000 full-time librarians and library media specialists in the 2015–16 school year, as well as an additional 17,600 part-time librarians and library media specialists.

  • Since there were more library media centers (82,300) than librarians and since some schools may employ more than one librarian, not every school with a library media center also employed a school librarian. On average, had 0.7 full-time and 0.2 part-time librarians and library media specialists.

 

Library media centers

  • In the 2015–16 school year, 91 percent of public schools had a school library media center. Overall, there were approximately 82,300 public elementary and secondary schools with a library media center.

  • The presence of school library media centers varied by the grade levels taught at schools. In the 2015–16 school year, higher percentages of primary schools (96 percent) and middle schools (95 percent) had library media centers than high schools (80 percent) or combined schools (79 percent).

  • The presence of school library media centers also varied by the type of community in which schools were located. About 88 percent of city-based schools had a library media center in the 2015–16 school year, which was lower than the percentage of schools located in suburban areas (92 percent) and rural areas (94 percent).

  • While the vast majority of public schools have a library media center, the percentage fell slightly between school years 2003–04 and 2015–16, from 94 percent to 91 percent, respectively (see Figure 1 below).

A Slightly More Diverse Public School Teaching Workforce

There is research evidence that having a teacher of the same race/ethnicity can have positive impacts on a student’s attitudes, motivation, and achievement[1] and that minority teachers may have more positive expectations for minority students’ achievement than nonminority teachers.[2] New data from the National Center for Education Statistics show that the public school teaching workforce is becoming more diverse, but is still predominantly White.

The majority of public elementary and secondary school teachers were White in both 2003–04 and 2015–16. However, the percentage of teachers who were White was lower in 2015–16 than in 2003–04 (80 vs. 83 percent). While the percentage of teachers who were Black also fell slightly in that time, the percentages of teachers who were Hispanic, Asian, and of Two or more races were higher in 2015–16 than in 2003–04.

See Digest of Education Statistics 2017, table 209.10.


 

The racial/ethnic diversity of teachers differed somewhat by school characteristics. For example, schools with more racial/ethnic diversity in their student populations also tended to have more racial/ethnic diversity among teachers. In 2015–16, the percentage of minority[3] teachers was highest at schools that had 90 percent or more minority students (55 percent) and was lowest at schools with less than 10 percent minority students (2 percent). The opposite pattern was observed for White teachers, who accounted for 98 percent of teachers at schools with less than 10 percent minority students but made up only 45 percent of staff at schools with 90 percent or more minority students.

Learning about Schools from Teachers and Principals

In the 2015-16 school year, there were approximately 90,400 principals and 3,827,100 teachers in public elementary and secondary schools in the United States. Knowledge about the characteristics and experiences of these key school staff can help inform decisions about education.  The National Teacher and Principal Survey (NTPS) supports these decisions by providing data on a variety of topics from the perspective of teachers, principals and other school staff. Results from these questionnaires provide information such as:

  • Principals’ education. Among public schools, a majority of principals held a master’s degree (61 percent) as their highest degree, compared to an education specialist/professional diploma at least one year beyond the master’s level (27 percent), a doctorate/first professional degree (10 percent), or a bachelor’s degree or less (2 percent).
  • Hours worked by teachers. On average, regular full-time teachers in public schools spent 53 hours per week on all school-related activities. That includes 27 hours that they were paid to deliver instruction to students during a typical full week. Public school teachers were required to work an average of 38 hours per week to receive their base pay.
  • Online courses. Nationwide, about 21 percent of public schools offered at least one course entirely online. This was more common among public charter schools (29 percent) than it was among traditional public schools (20 percent). A greater percentage of high (58 percent) and combined (64 percent) schools offered one or more courses entirely online than all public schools. It was also more common for schools with fewer than 100 students (45 percent) and schools with 1,000 or more students (44 percent). Among schools offering online courses, relatively more public charter schools offered all of their classes online (14 percent) than traditional public schools (5 percent).

A Closer Look at Teacher Income

Full-time teachers in public school earned an average of $59,050 from all income sources in the 2015–16 school year. This income includes teachers’ base teaching salary, as well as additional sources of income from their schools or districts, jobs outside the school system, and summer activities. To capture the different ways that teachers can earn income, the 2015-16 National Teacher and Principal Survey asked teachers questions about how much they earned from various sources:

  • Base teaching salary. Teachers’ average base teaching salary was $55,120 for the 2015-16 school year.
  • School supplement. About 44 percent of teachers received additional compensation for extracurricular or additional activities in their school system, such as coaching, sponsoring student activities, mentoring teachers, or teaching evening classes. These teachers earned an average of $2,630 for these activities.
  • Merit pay. Some teachers earned merit pay or pay-for-performance income based on their students’ performance. About 6 percent of teachers received this type of additional compensation, with an average amount awarded of $1,470.
  • Other school system support. About 8 percent of teachers received income during the school year from some other source in their school system, such as a state supplement, for an average of $2,670.
  • Outside jobs. During the 2015-16 school year, 18 percent of teachers held a job outside the school system, earning an average of $5,140. Teachers categorized these jobs as teaching or tutoring (5 percent), non-teaching but related to the teaching field (4 percent), or in another field (9 percent).
  • Summer jobs. In the summer of 2015, before the start of the 2015-16 school year, 20 percent of teachers earned income from either a school-based teaching position, such as teaching summer school, or a non-teaching position, and 16 percent earned income from a non-school job. Teachers earned an average of $2,700 from school-based summer positions, and an average of $4,060 in a non-school job.

To learn about teachers’ satisfaction with their teaching salary, more information is available in the short report Teacher Satisfaction with Salary and Current Job.
