The 18-26 window: Fordham, Wharton, and the family business

Donald Trump was born on June 14, 1946, in New York City. He graduated from the New York Military Academy in 1964 and enrolled at Fordham University in the Bronx, studying economics. After two years, he transferred to the Wharton School at the University of Pennsylvania, graduating in May 1968 with a BS in economics. He then began working full-time for his father's real estate company, the Fred Trump Organization. The ages 18-26 window covers his entire college career and his first four years in the family business.

Year-by-year achievement chronology

The table below lists each documented achievement during the 18-26 window. The record is notably thin on intellectual output. No published writing, no thesis, no academic honors, and no extracurricular intellectual activities are documented for this period.

Assessment and estimate

Strengths: Trump attended the Wharton School at the University of Pennsylvania, an Ivy League institution. He graduated with a BS in economics. Weaknesses: The record is striking for the absence of intellectual indicators. Trump did not graduate with any honors—not on the Dean's List (top 15%), and not listed as cum laude, magna cum laude, or summa cum laude in the 1968 commencement program. His claim to have graduated 'first in his class' has been investigated by the Daily Pennsylvanian and the Associated Press and is false. Classmates describe him as 'loath to really study' and coming to study groups unprepared. He did not participate in any extracurricular intellectual activities after his freshman year. He was not a member of any club, sports team, or fraternity at Penn. He was admitted to Wharton through a family connection—his brother's friend worked in the admissions office—and the school was 'not yet very selective' at the time. After graduation, he worked in his father's real estate company with no independent intellectual output. No published writing, no thesis, no academic distinctions are documented for the entire 18-26 window. Placement: In the Simonton distribution, the lowest II-C values are Grant at 130 and G.W. Bush at 138.5. Trump's record is comparable to or weaker than Grant's. An informal estimate of 130 places him at the bottom of the presidential range. This is consistent with a person who attended a selective university without distinguishing themselves academically and produced no evidence of intellectual precocity.

Donald Trump
What the evidence supports

Trump's ages 18-26 record shows minimal intellectual engagement. He graduated from Wharton without honors of any kind, produced no intellectual output, and classmates describe him as disengaged. The claim that he graduated 'first in his class' is false. An informal estimate of 130 places him near the bottom of the Simonton presidential distribution, comparable to Ulysses S. Grant.
