Treasure Valley residents have lukewarm opinions about the K-12 system, according to a Boise State University survey released Thursday.

While 48 percent of survey respondents rated their local K-12 schools as good or excellent, 37 percent of respondents rated local schools as fair or poor.

That leaves 15 percent of respondents, who either said they didn’t know how to rate their local schools, or refused to answer.

All told, the new numbers aren’t too different from Boise State’s 2016 survey. A year ago, 50 percent of Treasure Valley respondents rated local schools as good or excellent, 41 percent gave their local schools marks of fair or poor and the remaining 9 percent did not answer the question.

Education was a relatively small piece of this year’s survey, which focused largely on growth and public transit issues.

In September, Boise State surveyed 1,000 adults living in Ada, Boise, Canyon, Gem and Owyhee counties, using a survey sample designed to reflect the counties’ population. The survey margin for error is 3.1 percent.
