Alfred Ryll was McArthur's first principal, serving in that capacity into the 1960s. Mr. Todd J. Lapace was named the principal in 2010 until August 2019. Alfred Broomfield II was named as his successor to become the new principal of McArthur High School. The school was founded in 1957 at its current location. That first year saw classes of 7th through 9th grades. Many classes in the early years were held in portable classrooms although construction of the gymnasium, auditorium, cafeteria, library, and administrative offices was soon begun. The existing student body as well as the new 7th Grade class entering in 1958 were served by those new facilities, although there were still several portable structures on campus. Planning was already in progress for feeder schools, and in the Fall of 1959, the eventual Class of '64 left McArthur and attended Driftwood and Henry D. Perry Junior High Schools. In both cases, 8th Grade was in portable classrooms and 9th Grade was in new physical plants. Succeeding classes went directly to Driftwood and Perry. 1960 saw the first Senior Class graduating from McArthur and 1959/'60 saw the last 9th Grade class attending until the reorganization of the school structure. In the Fall of 1961, the last 7th Grade class to attend McArthur returned to complete their Sophomore, Junior, and Senior years. In 1967, McArthur played Ely in the season opener for both teams. This, along with another game in Broward County between Fort Lauderdale and Dillard the same night, was the first meeting between white and black teams. McArthur High has an FCAT school grade of "A" for the 2011-2012 academic year. The Boys Cross Country Team won the State Championship in 1964. The wrestling team won the 4A Florida High School State Championship in 1979 and the 3A State Championships in 1986, 88, and 89. The Girls Cross Country team won the 4A Florida High School State Championship in 1977,1978,1979 and 1980. The Girls Track and Field Team won the 4A Florida State Championship in 1978 and 1979. In 2012 the school was the scene of a mass casualty response from state and local authorities, responding to a call of a mysterious rash. The local hazmat unit and firefighters evacuated 12 students and 2 teachers to a local hospital with police escorts. The Hollywood hazmat unit tested several objects from desks to door knobs but found no conclusive source of the rash. At the local hospital 30 staff members were ready to receive the students and decontamination showers were setup to process the students and teachers. The school board decided to open the school for students the next day and the rash was eventually identified as a prank using itching powder. In 2019, the school hired Alfred Broomfield II.
