Teachers overwhelmingly support state academic standards — such as Common Core — but they are skeptical about the tests aligned to standards. That’s the takeaway from a new study from the RAND Corporation. In a February 2016 survey of more than 1,300 teachers nationally, 88 percent of respondents said they favored state standards for math, and 87 percent favored state standards in English language arts. Teachers in lower-income schools were more likely to support state standards.
