Founded in September 1961, and named for the Cardinal John Henry Newman, it is one of two private Catholic high schools in Palm Beach County, Florida.

In 2005, Cardinal Newman was the first Catholic high school in Florida, and one of only a dozen in the United States to offer the International Baccalaureate Diploma Programme.

St. Ann's School opened its doors in 1925 to serve parishes in central Palm Beach County.

This changed when Archbishop Coleman F. Carroll announced construction of a new high school in West Palm Beach.

Students can also partake in the IB Diploma Program or Advanced Placement courses offered at Newman.
