A shakeup in the security department of ACT Inc. is being reported after revelations about cheating overseas in a program run by the giant testing nonprofit organization.

Reuters, which has published a series of stories about cheating on high-stakes tests that students around the world take to get into college, has a new story that says ACT Inc. “is laying off its head of test security and plans to audit nearly 200 education centers” after revelations were published about cheating in the Global Assessment Certificate program, which is recognized by scores of U.S. admissions offices.

ACT Inc. owns the ACT test, which is now the most popular college admissions test in the United States, overtaking the SAT years ago. It also owns numerous other assessment and instructional improvement programs, including the Global Assessment Certificate that was the subject of a recent Reuters probe.

According to Reuters, Rachel Schoenig, the head of a 14-person security team, is leaving ACT next month — though it is not clear who will replace her or whether she will be replaced — and other top security officials have already left.

ACT spokesman Ed Colby said in an email that he could not discuss personnel issues.

This is the latest in a series of revelations by Reuters about security issues with the SAT and ACT programs, including the recent report about a large breach of hundreds of confidential questions from the newly designed SAT. Among the findings about the SAT:

* “Internal documents show that the U.S. college entrance exam has been compromised in Asia far more often than acknowledged. And the newly redesigned SAT retains a key vulnerability that the test-prep industry has exploited for years.”
* “Booklets for the redesigned exam leaked online within days of the test. The ongoing failures to secure the SAT are prompting some college officials to question the validity of exam scores.”
* “At least five times in the past three years, U.S. high school students were administered SAT tests that included questions and answers widely available online more than a year before they took the exam, a Reuters analysis shows.”

For years, the College Board, which owns the SAT, has been dealing with major security breaches that have resulted from sophisticated overseas cheating networks. They have thrived in part because the College Board has in the past used questions on overseas exam forms that already have been given in the United States, allowing test-prep companies to send people to the United States to take tests and/or obtain test questions by memorizing them or obtaining them illegally, as well as by monitoring chat boards where students post questions right after taking the tests.

The College Board canceled the administration of the SAT at some sites in China and Macau just hours before students were scheduled to take it last January because of a security breach. SAT scores have been withheld from some students at every single SAT administration in Asia for several years, and the scores from the entire May 2013 administration of the SAT and SAT Subject tests in South Korea were canceled because of a leak of questions.
