This publication, the most recent edition of a resource tool for students choosing colleges, makes recommendations for undergraduate programs in about 65 major subjects, most of which are divided among groups of schools based on their selectivity. The ranking of major fields of study was done primarily by students in colleges and universities nationwide, and college admissions officers and secondary school counselors also participated in the study. Approximately 2,600 entries with about 63 colleges per major are included. Each major field institution is ranked by "most selective,""very selective," and "selective" in terms of difficulty in gaining admission. The relative size of each school is included along with an indication of whether it is primarily for men, women, or mixed. A list of 12 helpful hints includes: do not overlook the good small liberal arts college; keep in mind that weak departments at places like Harvard and Yale might be equal to or better than the strongest departments at many colleges and universities; and many of the best of the more expensive schools are actually least expensive because they offer financial aid. Six appendices are: the 500 colleges used in the study; the miscellaneous majors colleges used in the study; men's colleges included in the study; women's colleges included in the study; a simplified time table and checklist for seniors planning on college; and the get-going form.
