Their website is at
America's Best Architecture & Design Schools 2009
It costs $40 to get the book with all of the info but I found excerpts at other places for example:
The Top U.S. Architecture Schools
and
College Ranked in Top Ten | College of Architecture, Planning & Design
I have purchased the pdf file for the past three years to see how the rankings change and the comments contained in the articles. Several schools were consistently in the top ten. Also I thought the students evaluations were interesting (they got 700 students to respond to a questionnaire about whether they would recommend their school) and the rankings within the major like sustainable design and cross discipline experience were valuable since my daughter is interested in interior design and architecture.
The rankings also show the rankings over the past several years so if you buy the latest version you will see how the schools have done in the past 5 or 6 years. I think it is worth the $ if you are serious about interior design, architecture, industrial design or landscape architecture.
