The Higher Education Coordinating Board has issued the newest edition of its annual report comparing undergraduate tuition levels for Washington schools with national and “peer state” averages.
For community colleges the tuition levels are roughly comparable ($2,730 for Washington versus a national average of $2,793). For four-year schools similar to the UW, the disparity is greater ($6,697 for Washington versus a national average of $7,481). That difference is ever larger when the UW is compared to “peer state” schools where tuition averages $8,681.
