In 1999, William "Sonny" Connors, grandfather to Derek Jeter and longtime head of school maintenance, died. In honor of Sonny's service to Queen of Peace, the Jeter family, through Jeter's Turn2 Foundation, started the Connors/Jeter Scholarship Fund. This fund was started to help exceptional, well-rounded students from Queen of Peace and to memorialize Derek's grandfather, William "Sonny" Connors, with two students meeting the criteria of academic and community accomplishments being chosen each year as recipients. On January 4, 2007, several Queen of Peace students traveled to Rome in order to sing in a private audience to Pope Benedict XVI. In February 2013, the school attracted national attention when it asked the girls of the school to take a pledge not to curse for 30 days as the school wanted "ladies to act like ladies", though male students at the school were asked not to swear "in the presence of ladies" and were not required to take an oath. Circa 2016 the school administration announced that it needed $1 million raised for it to remain open. Ultimately about $1,035,000 was raised and the school stayed open for another school year. The necessary money was generated in approximately one month. Despite the 2016 fundraising campaign, in May 2017, the Archdiocese of Newark announced the closing of the school as of June 30, 2017, in the wake of sharply dropping enrollment and financial challenges, though the affiliated K-8 grammar school will remain open.
The Queen of Peace High School Golden Griffins competed in the North Jersey Interscholastic Conference, made up of private and public high schools located in Bergen County, Passaic County and Hudson County. Prior to the league realignment that took effect in the fall of 2010, Queen of Peace had been a member of the American Division of the Bergen County Scholastic League. St. Mary High School filed a complaint against Queen of Peace High School with the NJSIAA in 2007, claiming that a new wrestling program run by former Gaels coach Scot Weaver at Queen of Peace would induce St. Mary's wrestlers to transfer schools. In 1980, the boy's soccer team won the NJSIAA Boys Non-Public “A” state championship. The 1989 Golden Griffins were the last football team to win the Bergen County Scholastic League championship. As BCSL American Division Champions, the Griffins went on to play Bergen Catholic in the NJSIAA Parochial School state playoffs. In 1990, the Golden Griffin football team battled Don Bosco Preparatory High School in the NJSIAA Parochial final, ultimately losing 21 - 20.
