Oregon is also extremely rural - Portland is the most populous city in the state by far, and its e.g. far smaller than all cities in the Houston/Austin/Dallas/SanAntonio metroplex. There's important cultural factors that impact its education too, like historic underfunding, poor education spending priorities, and out of touch unions (many days off, striking mid year for funds that aren't there). But I always felt the rural-ness impacting wider education trends was very under represented in discourse.
