How many schools in wa?

The exact number of schools in Washington state is difficult to pin down to a single number because of different definitions of "school." There are different types of schools (public, private, charter, etc.) and various reporting agencies use slightly different methodologies.

To get a reasonable estimate, you'd need to consult the Washington State Office of Superintendent of Public Instruction (OSPI) for public schools and then separately research private schools, which is a more fragmented data set. You won't find a single, official number readily available.
