The purpose of this state report card is to provide the general public and policymakers with information they can use to assess and improve postsecondary education in each state. "Measuring Up 2006" is the fourth in a series of biennial report cards. The report card grades states in six overall performance categories: (1) Preparation: How adequately does the state prepare students for education and training beyond high school?; (2) Participation: Do state residents have sufficient opportunities to enroll in education and training beyond high school?; (3) Affordability: How affordable is higher education for students and their families?; (4) Completion: Do students make progress toward and complete their certificates or degrees in a timely manner?; (5) Benefits: What benefits does the state receive from having a highly educated population?; and (6) Learning: What is known about student learning as a result of education and training beyond high school? Findings for Washington include: (1) Washington has made progress in preparing students to succeed in college. This year Washington receives a B in preparation; (2) Washington has seen a decline in the proportion of students enrolling in higher education. Washington receives a C- in participation this year; (3) Washington has made no notable progress in providing affordable higher education. Washington receives a D- in affordability this year; (4) Washington has made gains in the proportion of students who earn a certificate or degree in a timely manner. Washington receives an A in completion this year; (5) Washington has seen a substantial increase in the benefits the state receives from having a more highly educated population. This year Washington earns an A- in benefits; and (6) Like most states, Washington receives an "Incomplete" in Learning because insufficient data would not allow meaningful state-by-state comparisons. However, data are available this year to examine the readiness of college graduates--from two- and four-year institutions--for advanced practice. This report also includes international comparisons, additional information, questions and answers, and state grades. (Contains 3 figures.) [For "Measuring Up, 2006.
