NCES Blog

In this two-part blog series, we’ll discuss the role of NCES as the primary federal entity for collecting and analyzing essential education data in the United States and highlight a specific NCES survey—the National Teacher and Principal Survey (NTPS)—which is designed to support state and district policymakers.

Federal, state, and district decisionmakers need reliable, trustworthy data to inform education funding and policy regulations. In order to enact good laws that best serve all of our students and school staff, they need data that are as diverse and representative as our schools. As a federal statistical agency, NCES fulfills a Congressional mandate to collect, analyze, and report statistics on the condition of U.S. education and is the primary source that policymakers and other decisionmakers rely on for education data. These efforts include administrative data collections and cross-sectional, longitudinal, and assessment surveys that gather information to help the education sector better understand early childhood, K–12, and postsecondary education nationally and internationally.

The NTPS exemplifies the utility of NCES data. NTPS data are available both nationally and by state (via the NTPS State Dashboard and DataLab) and are used by policymakers and researchers to make funding and other policy decisions. NCES also helps decisionmakers, researchers, and the public use and make sense of the data by providing access to NTPS datasets and publishing reports, such as numerous NTPS reports, the Condition of Education, and the Digest of Education Statistics.

The NTPS collects data about school conditions and the demographics of public and private K–12 teachers and principals directly from school staff themselves, providing critical data on educators’ perspectives and experiences in schools every day.

The NTPS has been collected in one form or another since 1987–88—when it was known as the Schools and Staffing Survey (SASS)—and was last conducted during the 2020–21 school year amid the coronavirus pandemic. The 2023–24 NTPS is currently being conducted.

Let’s use the NTPS to answer a few common questions about the role of federal education data.

1. Why do federal data matter to district policymakers if states and districts have their own local collections?

In a postpandemic world cleaved into “before” and “after,” policymakers at all levels need information on the condition of education across the country to craft policies that are truly reflective of the needs, challenges, and strengths of students and staff.

Since education in the United States is primarily a state and local responsibility, it can be difficult to make comparisons between states if we don’t have a federal agency collecting the data in a systematic and comparable way across the country. The NTPS, for example, publishes both public school data at the national and state levels and representative public and private school, principal, and teacher data for several characteristics (e.g., type of community in which a school is located; percentage enrollment of students of color; staff characteristics like race/ethnicity and years of experience).  

Figure 1 shows an NTPS-based example of how using common questions across all school systems supports important cross-state comparisons. This is just one of hundreds of similar comparisons that have been made using NTPS data on topics such as teachers’ classroom experiences and principals’ challenges filling needed teacher vacancies. Comparisons can also focus on different school, principal, and teacher characteristics (e.g., type of community in which a school is located; level of training for staff; race/ethnicity of staff).

The primary responsibility of state or district education decisionmakers is to use trustworthy data to support the needs of their local schools and families Thankfully, state, district, and school leadership don’t need to assume the full financial and logistical responsibility on their own when there are federal data available that can help with state and local data needs. The same federal education data underpinning congressional funding decisions, policy choices, and guidance can be used for numerous state, district, and school policy and practice decisions as well—if education leaders know where to look.

Federal, state, and district education agencies and schools all serve different roles in the education sector but have similar and mutually beneficial responsibilities and goals on behalf of students and school staff (figure 2).

NCES and its predecessors have been congressionally mandated since 1867 to collect, analyze, and report data on the condition and progress of U.S. education for policymakers to use as a tool when making decisions to support our students and our school staff. National and state-level estimates from NCES surveys support state and district data efforts and strategic goals. For example, the California State Senate used state-level NTPS school start time data¹ to inform SB:328 (a bill to require California school districts to shift middle and high school start times to no earlier than 8:30 a.m.), which was passed in 2017 and amended in 2021.  

2. How do federal data benefit everyone in the education sector?

NCES produces unique data and information products that rely on statistics produced from data collected through state or district records and a suite of surveys, the majority of which come directly from responses given by educators, students, and families. For example, NCES produces an annual report to Congress called the Condition of Education. The Condition of Education summarizes and makes sense of data from more than 25 data collections administered by NCES and other government agencies. Federal policymakers also rely on other NCES reports, such as the annual Digest of Education Statistics, Projections of Education Statistics, and Report on Indicators of School Crime and Safety. For an example of the indicators available in the Condition of Education, see the figure below, which is from Characteristics of Traditional Public, Public Charter, and Private School Teachers.
