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 Massachusetts include: (1) Massachusetts has improved on its already excellent performance in preparing students to succeed in college. This year Massachusetts receives an A in preparation; (2) Despite a decline in performance, Massachusetts continues to excel in enrolling students in higher education. This year Massachusetts receives an A in participation; (3) Massachusetts has made no notable progress in providing affordable higher education. This year Massachusetts is one of many states to receive an F in affordability; (4) Massachusetts has made notable gains in the proportion of students earning a certificate or degree in a timely manner. Massachusetts receives an A in completion this year; (5) Massachusetts has seen an increase in the benefits the state receives from having a more highly educated population. Massachusetts earns an A in benefits this year; and (6) Massachusetts is among nine states that receive a "Plus" in Learning because data were sufficient to compare at least two of the three Learning categories in the state results described in this paper. This report also includes international comparisons, additional information, questions and answers, and state grades. (Contains 3 figures.) [For "Measuring Up, 2006.
