The Golden Knights have been a member of ECAC Hockey since 1962, and play their home games at Cheel Arena in Potsdam, New York.

The program continued to build until they produced a superb 23–0 record in 1956 with NCAA scoring champion Ed Rowe leading the way.

'Tech' finally received an NCAA invitation but it came with a caveat; because eight of their players were 4-year lettermen they would have to sit out the tournament for Clarkson to participate.

[4] The Golden Knights wouldn't have to wait long for their first tournament appearance, however, as they were invited the following year and finished in third place.

After a second consecutive third-place head coach Bill Harrison resigned and turned the team over to Len Ceglarski.

The first few years under Ceglarski saw the team's record dip slightly but stating in his third season the Golden Knights became a constant power in college hockey.

In the tournament Clarkson faced relatively weak opponents (the 4th- and 6th-place teams from the WCHA) and though they managed to win their semifinal matchup, they couldn't take advantage in the title tilt and fell to Michigan State 1–6.

After defeating the top western team in the semifinal, Clarkson faced off against the undefeated Cornell Big Red and fought tooth and nail for their first championship.

The following year Clarkson finished in second place for both the ECAC and their conference tournament but received a slap in the face from the selection committee when they were passed over for Boston University as the second eastern team.

A year later Len Ceglarski would leave the program to take over at his alma mater Boston College, having led Clarkson to 12 consecutive seasons of at least a .600 winning percentage.

It took four years for Tech to climb back to its lofty perch and in 1977 it did just that with future NHL all-star Dave Taylor leading the way.

Unfortunately the team hit a roadblock in the semifinal, losing to Boston University 6–7 and finished the ECAC tournament in 4th place.

Despite the top finish Clarkson received no respect from the selection committee and was seeded 4th in the eastern bracket despite having a better record than the 2nd- and 3rd-seeded schools.

Clarkson was expected to continue this trend for years to come but in November 2002 Morris was suspended following an altercation with one of his players after a team practice.

Parker was replaced by George Roll they following year and after a slow start, the Golden Knights recovered and finished as runner-ups in the ECAC tournament.

Roll was fired in 2011 with the program at its nadir, becoming the only full-time head coach to finish his tenure at Clarkson with a losing record.

[8] On June 13 2024, it was announced that Casey Jones would leave the program to return to his alma mater, Cornell, as a Head Coach Elect.
