According to USNews, as of 2018, Rutgers’ graduate CS program is ranked #37 tied with the likes of UC Davis and UC Santa Barbara. However, there are other ways to judge the strength of a school’s CS program. For example, one could ask how many papers has Rutgers published in the area of computer science in comparison to other schools?
In AI, Rutgers ranks #17 in most papers published. In Systems, Rutgers ranks #36 in most papers published. In Theory, Rutgers ranks #38 in most papers published. In Interdisciplinary Areas, Rutgers ranks #25 in most papers published.
Note that there is a positive correlation between the size of a school’s faculty and the number of a school’s publications. More faculty equals more publications. The size of Rutgers’ CS faculty is relatively small to that of the elite CS schools.
If you’re interested in the number of papers published by different schools, I would recommend checking out the site I used in this answer, CSRankings, and play with the settings. Generally I look at the total number of publications in the largest time span possible, which is currently from 1970–2018 but this can be changed to fit your curiosity.
