McLaughlin placed a close second behind Shamier Little in the 400-meter hurdles at the national junior (under-20) championships in 2014; her time of 55.63 was a national high school freshman record and a world age-14 best. She would have qualified to represent the United States at the 2014 IAAF World Junior Championships, but was a year too young to be eligible. McLaughlin also set a world age group best (13.34) in the 100-meter hurdles over 76.2 cm (2 ft 6 in) hurdles that summer.
In November 2016, McLaughlin signed a National Letter of Intent to attend the University of Kentucky and compete for their track and field program.
McLaughlin was part of an American Record quartet that broke the indoor distance medley relay world record with a time of 10:40.31, set at the New Balance Indoor Grand Prix on January 28, 2017. The splits for the four legs were: 3:18.40 (1200 m) by Olympic medalist Emma Coburn,52.32 (400 m) by McLaughlin, 2:01.92 (800 m) by Brenda Martinez, and 4:27.66 (1600 m) by Olympic medalist and former world 1500m champion Jenny Simpson. Later that indoor season, McLaughlin lowered her own national 400-meter record to a 51.61 at the New Balance Nationals in New York City on March 12, 2017.
In April 2017, McLaughlin continued the positive momentum from the 2017 indoor campaign by opening her outdoor season in style—breaking the 300m hurdles national high school record at the Arcadia Invitational running 38.90. The record was previously held by Lashinda Demus who ran 39.98 in 2001. The record was the first ever attempt over 300m hurdles for McLaughlin as high school track meets in New Jersey do not contest the 300m hurdles. Her time of 38.90 is considered to be a North American Record and number 2 all-time worldwide behind Zuzana Hejnova who ran 38.16 in 2013. Later that month, McLaughlin ran the fastest ever high school girls (400m) relay split during the Championship of America high school girls 4x400 at the 123rd Penn Relays. After taking the baton at the back of an eight-team field, McLaughlin posted a split of 50.37, passing five teams to lead her Union Catholic relay team to a third-place finish in 3:38.92. She bettered this mark at the New Balance Nationals Outdoor Meet on June 18, 2017. Taking the baton in 6th place on the final handoff, she passed five runners to lead Union Catholic to victory, posting a split of 49.85 seconds.
In March 2018, McLaughlin set world junior 400-meter record in (50.36) at 2018 NCAA Division I Indoor Track and Field Championships.
On May 13, 2018, McLaughlin broke the collegiate and NCAA record in the 400-meter hurdles, running 52.75 to win the event in her first SEC championship appearance.
In October 2018 she turned professional, and signed with the New Balance team.
