⁵ Each of the selected states—Alabama, Colorado, Connecticut, Illinois, Iowa, Pennsylvania, Virginia, Texas, and Washington—represents one of the nine regional divisions used by the US Census, reflecting our desire for a mix of political, administrative, and social contexts shaping education. In the full report, we include an appendix describing the differences in partisan politics, state agency authority, social studies assessment, and labor and licensure rules across these nine state contexts. The data collection for this project took place between spring of 2022 and summer of 2024.

⁶ To assemble a corpus of state laws, AHA researchers used a variety of databases, including HeinOnline, LexisNexis, and state legislative websites. The legislative database, while not exhaustive, provides a wide sample of the variety of approaches that legislatures have taken to affect social studies instruction.

⁷ Using AHA, NCSS, National Council for History Education, and National History Day networks and cold calls, we recruited and interviewed 205 educators (147 teachers and 58 administrators) across our nine sample states. All interview subjects signed an agreement confirming their consent to be interviewed and affirming the research team’s commitment to protecting their anonymity; all interview materials (notes, releases, and identifying information) will be retained as confidential documents for sixty years, and then transferred to the AHA Archive. In April 2023, the AHA contracted with the National Opinion Research Center (NORC) at the University of Chicago to conduct an online thirty-minute survey of public middle and high school US history teachers in those same nine states. The survey elicited detailed information on multiple topics: teaching environment; background (years of teaching experience, highest academic degree); the role of curricular directives from the school, district, and state; materials used for teaching US history; familiarity with various free history teaching resources; teaching goals and values; and which areas participants find most important, most rewarding, and most challenging to teach. Teacher contacts for the survey came from a leased directory of teachers from MDR Education, a division of the commercial analytics company Dun & Bradstreet. Between April and August 2023, the survey hit the field, ultimately collecting usable responses from 3,012 participants. The number of teachers returning the survey in either “complete” or “partial” form represented a 13 percent response rate. Special care was taken by NORC to assess the social representativeness of the survey sample—both with regard to teachers and the environments they work in. For teachers themselves, this was achieved using data from the National Teacher and Principal Survey on the teacher population with respect to racial/ethnic background, gender, teaching experience, and degree attainment. For school settings, this was achieved by using Common Core Data figures on free and reduced price lunch recipients and percentages of nonwhite students in school populations. As NORC asserted, the analyses give “some confidence that the survey respondents are generally representative of US history teachers in the different types of locales and student grade levels,” as well as “some confidence that the AHA respondents are drawn from a set of schools that reflect the demographics of their respective states and locales.”

⁸ Scholarly consensus is a moving target, of course, but historians mark the factual and interpretive boundaries of their subfields in a range of formats: volumes of narrative synthesis; historiographic essays; state-of-the-field articles; “major issues” handbooks; and more.

The New American History (Philadelphia: Temple University Press, 1997); Eric Foner and Lisa McGirr, eds., American History Now (Philadelphia: Temple University Press, 2011); Elizabeth Cobbs and Edward J.

¹⁴ While low overall, rates of reported experience with direct criticism among surveyed teachers revealed some correlation with the social profile of their communities. Teachers working in wealthier districts (as measured by the rates of students who qualified for free or reduced lunch) were the most likely to report having experienced objections “several times” over the course of their career. (This group made up 17 percent of surveyed teachers.) Meanwhile, teachers working in low-income districts were far more likely to report that they had never experienced any criticism (51 percent). Suburban teachers, among all locales, were the least likely to say that their careers were without challenge, while teachers in other locales showed little variation. An important caveat: aside from standards and legislation, our study could not capture conditions outside of our nine sample states—or outside of the time that we spent on the project. If, as we note, political flare-ups are local and contingent, then it’s altogether possible that things might be worse (or better) beyond the boundaries of the times and places we studied.

¹⁵ On goals, “Survey of US History Teachers,” AHA/NORC questionnaire, 2023, question 34. In our survey, we asked teachers to register their familiarity and usage of over two dozen digital US history teacher resources. Only a small handful provoked negative reactions. Of those, the only resources that earned suspicion from surveyed teachers because of what they or others judged as an ideological bias were the Pulitzer Center’s 1619 Project Education Network and The Hillsdale 1776 Curriculum. “Survey of US History Teachers,” AHA/NORC questionnaire, 2023, question 34.

¹⁷ Of the twenty-one states with a testing mandate for US history on the books, only twelve have stakes for districts or schools with regard to state accountability evaluations; only seven have stakes for students with regard to graduation. Among our sample states, Texas was the clear outlier in terms of its accountability environment, having the most detailed standards, the most unified assessment regime, and the highest-stakes accountability system for districts. As we discovered, Texas’s system produced strong trickle-down effects on local paperwork and benchmark testing. Seventy-four percent of Texas teachers we surveyed reported that they and their department colleagues gave a common test at the end of every curricular unit, compared with only 33 percent in other surveyed states.

¹⁸ Sixty percent of surveyed teachers said they actually use state standards directly in their teaching—although there are important differences from state to state. Over three-quarters of teachers in Alabama, Texas, and Virginia report using their state standards, while half or fewer teachers in Connecticut, Illinois, and Pennsylvania said the same. Interviews are cited here as either HST (for high school teacher), MST (for middle school teacher) or SSA (for social studies administrator).
