Central High School is a public high school in the Logan^[3] section of Philadelphia, Pennsylvania. Founded in 1836, it is a four-year university preparatory magnet school.

About 2,400 students attend grades 9 through 12. Central High School is the only high school in the United States with authority, granted by an 1849 Act of Assembly of the Pennsylvania General Assembly, to confer academic degrees upon its graduates.^[4] This authority to grant academic degrees led Central to refer to the principal of the school as the “President” of Central High School. The current and fifteenth president of Central High School is Katharine S. Davis.^[5]

Central, rather than using a general class year to identify its classes (as in "class of 2021"), uses the class graduating number system (as in "280th graduating class" or "280"). This tradition started shortly after the school's founding when it was common to have two graduating classes per year – one in January and one in June. In June 1965, semiannual graduations were replaced by annual graduations. As of the 2024–2025 school year, the current senior class is 284.^[6]

Central High School of Philadelphia was founded in 1836 as "the crowning glory" of Philadelphia's public school system, "the worthy apex to a noble pyramid," and the first "high" school in the state. Because city voters only reluctantly had been convinced of the need for a high school, the curriculum was carefully and publicly geared to the needs of taxpayers. Central's founders made an especially concerted effort to avoid educating students in the manner of private academies of the day, where classical languages and literature were of paramount importance.^[7]

The school was chartered by an Act of Assembly and approved on June 13, 1836. A site was purchased on the east side of Juniper Street below Market Street, and the cornerstone was laid on September 19, 1837. The school opened on October 21, 1838, with four professors and sixty-three students.^[8]

In November 1839, Alexander Dallas Bache, great-grandson of Benjamin Franklin, and Professor of Natural Philosophy and Chemistry at the University of Pennsylvania, was elected the first President of Central High School.^[9] President Bache resigned in 1842 to return to his professorship at the University of Pennsylvania, and was succeeded by John Seely Hart, who had been a professor of languages at Princeton University.^[8]

An Act of Assembly approved on April 9, 1849, provided that:

"The Controllers of the Public Schools of the First School District of Pennsylvania shall have and possess power to confer academic degrees in the arts upon graduates of the Central High School, in the City of Philadelphia, and the same and like power to confer degrees, honorary and otherwise, which is now possessed by the University of Pennsylvania."^[10] In accordance with this Act, the Board of Controllers on September 11, 1849, authorized the conferring of appropriate degrees upon graduates of Central High.^[8]

In September 1854, the school transferred to a new building, located at the southeast corner of Broad and Green Streets. In 1858, President Hart resigned and was succeeded by Nicholas Harper Maguire.^[8]

In October 1891 a Graduate Course in Pedagogy, later called the Philadelphia School of Pedagogy, was added to Central as a teacher training program for men.^[6] The School of Pedagogy was disbanded in 1918 due to numbers of enrollees dwindling as a result of World War I.^[11]

In September 1900, the school moved to its third location in a newer and larger building located at Broad, Green, Fifteenth, and Brandywine Streets.^[8] During the formal dedication on November 22, 1902, Theodore Roosevelt, President of the United States, addressed the students.^[12]

After 139 years of existence as an all-male public high school, Central's all-male policy was challenged by Susan Vorchheimer, who wished to be admitted to Central. On August 7, 1975, U.S. District Court Judge Clarence C. Newcomer ruled that Central must admit academically qualified girls starting in the fall term of 1975. The decision was appealed, and the Third Circuit Court ruled that Central had the right to retain its present status.^[13] The case eventually reached the U.S. Supreme Court that, on April 19, 1977, upheld the Third Circuit Court's verdict by a 4 to 4 vote with one abstention. That Supreme Court case was called Vorchheimer v. School Dist. of Philadelphia.^[14][15]

In August 1983, Judge William M. Marutani of the Philadelphia County Court of Common Pleas, ruled that the single-sex admission policy was unconstitutional. The Board of Education voted not to appeal the legal decision, thereby admitting girls to Central High School. In September 1983, the first six girls, all seniors, were admitted.^[16]

In October 1987, and again in September 2011,^[17] Central High School was officially named a Secondary school of National Excellence by the United States Department of Education and named a Blue Ribbon School. In March 1992, Redbook magazine named Central one of the best schools in Pennsylvania. Central was named "Best Secondary School in Pennsylvania" by the magazine each year since they began rating the nation's best schools.^{[citation needed]}

Since graduates are usually identified by class number, the year they graduated is not immediately apparent. This section explains the relation between class number and graduation date.

The first class graduated in June 1842. Through much of the school's history, there were two graduating classes per year, in January and June. However, there was only one graduating class in June in some years, including all years after 1965. The following list details the correspondence between class number and graduation date.^[18]

  1 June 1842
  2 June 1843
  3 January 1844
  4 June 1844
… 2 classes per year …
 75 January 1880
 76 June 1880
 77 June 1881
 78 June 1882
 79 January 1883
… 2 classes per year …
 95 January 1891
 96 June 1891
 97 June 1892
… 1 class per year …
116 June 1911
117 January 1912
118 June 1912
… 2 classes per year …
223 January 1965
224 June 1965
225 June 1966
… 1 class per year …

Thus, for classes graduating after 1965, if one knows the class number, one can determine the year of graduation by adding 1741. Conversely, if one knows the graduation year, one can determine the class number by subtracting 1741.
