Harvard University is investigating allegations that almost half the students in an undergraduate class last spring may have plagiarized or "inappropriately collaborated" on their final exams, the school announced Thursday.
Following an initial investigation, Harvard's administrative board, which enforces academic regulations, undertook "a comprehensive review of the more than 250 take-home final exams" submitted at the end of a course, the school said in a statement.
The Harvard Crimson, the school's flagship student-run newspaper, identified the class in which the cheating allegedly occurred as Government 1310: Introduction to Congress.
A document on the website of Harvard's registrar's office says the class had 279 students.
"We take academic integrity very seriously because it goes to the heart of our educational mission," said Michael D. Smith, dean of the faculty of arts and sciences, in a written statement.
