I don't see any mystery money or "govt accounting". I read the study, the article doesn't list all the components of total compensation. For example, paid time off is not listed in the article but it is an element of compensation.

This is a conversation starter but not a representative study, the article states as much even though the headline leads somewhere more conclusive. From the study: "Oregon alone has 197 school districts; the eight districts chosen are hardly representative or typical, and should not be taken as such." Also, the comparative communities have varying costs of living, would one expect to be paid the same--in any profession--working in Boise vs. Portland vs. Seattle? So, let's have the conversation but hold off on conclusions just yet.
