METHODOLOGY.

THIS IS THE 11TH ANNUAL EDUCATION NEXT SURVEY in a series that began in 2007. Results from all prior surveys as well as interactive graphics displaying the results are available at educationnext.org/edfacts.

The results presented here are based upon a nationally representative, stratified sample of 4,214 adults (age 18 and older), which includes representative oversamples of the following subgroups: parents with school-age children living in their home (2,170), teachers (669), and Hispanics (805). Respondents could elect to complete the survey in English or Spanish; 322 respondents elected to take it in Spanish. Survey weights were employed to account for nonresponse and the oversampling of specific groups.

The survey was conducted from May 5 to June 7,2017, by the polling firm Knowledge Networks (KN), a GfK company. KN maintains a nationally representative panel of adults (obtained via address-based sampling techniques) who agree to participate in a limited number of online surveys.

We report separately on the opinions of the public, teachers, parents, African Americans, Hispanics, white respondents with household incomes below $75,000, white respondents with household incomes of $75,000 or more, white respondents without a four-year college degree, white respondents with a four-year college degree, and self-identified Democrats and Republicans. We define Democrats and Republicans to include respondents who say that they "lean" toward one party or the other. In the 2017 EdNext survey sample, 53% of respondents identify as Democrats and 43% as Republicans; the remaining 4% identify as independent, undecided, or affiliated with another party. These percentages are similar to those obtained in the first EdNext survey in 2007, when 53% identified as Democrats and 42% as Republicans.

In general, survey responses based on larger numbers of observations are more precise, that is, less prone to sampling variance than those made across groups with fewer numbers of observations. As a consequence, answers attributed to the national population are more precisely estimated than are those attributed to groups. The margin of error for binary responses given by the full sample in the EdNext survey is roughly 1.5 percentage points for questions on which opinion is evenly split. The specific number of respondents varies from question to question, owing to item nonresponse and to the fact that, in the cases of several items, we randomly divided the sample into multiple groups in order to examine the effect of variations in the way questions were posed. The exact wording of each question is displayed at www.educa-tionnext.org/edfacts. Percentages reported in the figures and online tables do not always sum to 100, as a result of rounding to the nearest percentage point.
