Following retirement in 1970, Fullerton remained active with summer youth hockey camps, coaching US entry in the FIS World University Games (Lake Placid, NY). He also worked as a college scout for the
New York Islanders (1972-'77) and the
Chicago Black Hawks ('77-'78). In 1978, Hastings House Publishing Co. printed and marketed 8,000 copies of Fullerton's book
Ice hockey: Playing and Coaching. A driving force behind the
American Hockey Coaches Association from his arrival at Brown, presiding over the organization in 1967-'69, Fullerton received the AHCA Founders Award in 1989 and the "Jim Fullerton Award" is presented annually to recognize an individual who loves the purity of the game. Both Brown ('74) and Norwich ('84) Athletic Halls of Fame have inducted Fullerton. In 1989 he received the
Hobey Baker Legends of College Hockey Award, and Northwood School's Wall of Fame is in his recognition. The U.S. Hockey Hall of Fame honored Fullerton along with his good friends and peers,
Len Ceglarski and
Amo Bessone, as enshrinees in 1992. He was inducted into the Rhode Island Hockey Hall of Fame in 2020. Fullerton died March 3, 1991. He is buried at
Arlington National Cemetery in recognition of his more than 30 years of service as an active and reserve officer of the United States Army. ==Head coaching record==
