@brownie777, important to understand that the Princeton Review DOES NOT rank majors; they do rank many other characteristics of schools https://www.princetonreview.com/college-rankings/ranking-methodology
The Princeton Review’s College Ranking Methodology
Our 62 annual college rankings lists are entirely based on what students attending the schools in our Best Colleges book tell us about their colleges and their experiences at them via our student survey for this project. Each ranking list reports the top 20 colleges (of the 382 in the book) in a specific category.
We tallied the rankings lists in the current edition, The Best 382 Colleges (published August 2018), based on the data from our surveys of 137,000 students at the 382 schools in the book. Our student survey has 80 questions in four sections. We ask students about: 1) their school’s academics/administration, 2) life at their college, 3) their fellow students and 4) themselves. Students answer by selecting one of five answer choices that range across a grid or scale. The answer choice headers might range from “Strongly Agree” to “Strongly Disagree” or “Excellent” to “Poor”: some are percentages with ranges from “0–20%” to “81–100%.” This answer choice five-point scale—which is called a Likert scale—is the most commonly used measurement for this type of survey research: a consensus-based assessment.
We give each college a score for its students’ answers to each survey question. Similar to a GPA, it is a metric that provides us with a numerical base to compare student opinions from college to college—apples to apples, as it were. Using these scores (which we compute out to several percentage points), we are able to tally our ranked lists. Schools that make it onto any of our 62 top 20 lists are those at which the surveyed students (as a group) indicated a very high consensus of opinion about that topic.
Most of our ranking lists are based on students’ answers to one survey question, such as “How do you rate your campus food?” Some, such as our “Best Classroom Experience” list, are based on students’ answers to more than one question.
Note: The Princeton Review does not rank the schools in the book overall, 1 to 382, hierarchically or in a single list category. The Princeton Review reports the top 20 schools (of the 382 in the book) for each of its 62 different ranking list categories—but does not report ranks beyond the top 20 in any category (i.e., schools ranked 21 to 382).
Note: No ranking list reflects The Princeton Review’s opinion of (or rating of) the colleges. A college’s appearance on a ranking list in the book is entirely the result of what its own students surveyed by The Princeton Review reported about their campus experiences as well as how they rated various aspects of their college life.
Note: The Princeton Review college rankings are different from The Princeton Review college ratings. Our college ratings are numerical scores on a scale of 60–99 that we give to all colleges in the book. We report those rating scores in eight categories, including Admissions Selectivity, Financial Aid, Fire Safety and Green. Unlike our 62 ranking lists, which are based entirely on our student surveys, our eight rating scores are based primarily on our surveys of administrators at the schools who annually provide us with institutional data we request about their colleges. (A few of our rating scores factor in some of our student survey data—e.g., our “Professors Accessible Rating” score is based on students’ answers to our survey question that asks students to rate the accessibility of their professors on our five-point scale). Our college ratings scores appear in our school profiles in The Best 382 Colleges (as well as in our school profiles in our books Colleges That Pay You Back and The Complete Book of Colleges) and on our site. Learn more about our ratings here.
The Princeton Review’s 62 college ranking lists cover nine general areas: Academics/Administration, Quality of Life, Politics, Campus Life, Town Life, Social Life, Extracurriculars, Social Scene and Schools by Type. Here is a breakdown on each of those eight general areas, the titles of the ranking lists we report in each area, and information about each ranking list basis: the student survey question(s) we use to report the list.
Here’s the link to the Princeton Review page which lists the 330 schools which they have determined have an International Relations program https://www.princetonreview.com/college-search/?majors=45.0901. As has been noted on other threads, the list doesn’t include the University of Michigan which has a well known program so it is not comprehensive https://lsa.umich.edu/polisci/research/international-relations-and-world-politics.html
