The purpose of college and university ranking mainly resides to assist with the students in choosing their schools and programs at the level they wish to study. The US News and World Report (USNWR) graduate programs ranking is notable that evaluates the graduate level programs uniquely and in contrast with other general subject rankings. Along with the reputation of source, this specificity enables to enjoy a number of subscribers in making an application decision about which school or program is competitive and personally fits. Given the study of national research council is most exhaustive and authoritative ranking source on research doctorates, called Ph.Ds, the ranking of professional schools, for instance, law schools, medical schools, nursing schools and on, as presented to the students in USNWR is very determinative in deciding which school I choose. In this light, the following tables show a ranking that has been yielded on the diversity and quality of graduate and research doctorate programs as well as law studies specifically. Therefore, the tables can be referred to a vast of interested people on the graduate studies in the United States. The last part of reference can be referred not only by JD students, but also by researchers in the graduate law programs. Since some small or exclusively JD-oriented law schools are not available of LL.M or graduate study, the users of table are expected to read consciously. The ranking table has a threshold to qualify so as to be enlisted that the top 44 law schools in all specialties exclusively had been selected and ranked according to the average of two subjects. As said, it could be used secondarily to refer in deciding the schools on the application of general LL.M program. Given the junior scholarly nature of LL.M. or graduate law programs, it is considered that the legal writing program is half factored to select the schools. The column 1 and 2 transcribes the US ranking, which are added for a sum in column 3. Least number is placed at top and less number attains a high ranking correspondingly thorough the end of institution. The first and second parts of this work show the top universities according to the number of programs, whose possible highest rating is placed within the range 1st -17th in either R or S rank of most recent 2010 NRC assessment and roughly same range in the USNWR graduate programs ranking. They are prepared from the revised NRC report published in 2011, which is most recent as well as based on the 2021 version of USNWR. Both data will be incorporated into my current project concerning the American higher education and graduate studies.
