Jewish Students Accused of Cheating Are Expected to Turn Themselves In

At least seven people are expected to turn themselves in to the authorities next week on allegations of cheating on college admissions exams, according to a person briefed on the matter, as part of a scandal on Long Island in which students are accused of paying people to take the SAT reasoning test and the ACT test for them.

According to the person with knowledge of the situation, who lacked the authorization to speak publicly and spoke on condition of anonymity, at least three accused test-takers and four people accused of paying for stand-ins were expected to surrender on Tuesday, though the total number of people could be as high as 13.

Students at five schools, two public and three private, are believed to have been involved in this scandal, which has set off a sharp debate about the security measures on college admissions tests.

In an e-mail late Friday, Madeline Singas, the chief assistant district attorney in Nassau County, declined to comment.

The first arrest in the investigation was made on Sept. 27, when Sam Eshaghoff, a 2010 graduate of Great Neck North High School, was accused of taking college admissions tests for six students at his alma mater. Authorities said the students paid him up to $2,500 for taking their tests, and they were also arrested.

Prosecutors have said that Mr. Eshaghoff took the tests using a borrowed driver’s license and fake school ID cards — including one for a girl.
