"He was discontinued on May 25, 1996," said Janice Wiley, the academic-records assistant.
That means Tovar didn't register to finish his required coursework, she said. Before then, Tovar had been enrolled in the school's College of Arts & Sciences, where he'd pursued a degree in art.
Dan Bartlett, executive vice president of corporate affairs for Bentonville, Arkansas-based Wal-Mart, referred questions to Tovar.
"I'll let him speak to anything about his background," Bartlett, who is Tovar's boss, said on Tuesday. Tovar didn't respond to questions about his academic record.
Tovar managed communications on topics as diverse as sustainability, food stamps and the ongoing probe into Wal- Mart's alleged violations of the Foreign Corrupt Practices Act. In February, Wal-Mart broadened his responsibilities to include communications across all of its US businesses.
Tovar gained attention this year by criticising the New York Times on Wal-Mart's blog. He posted a copy of a "wildly inaccurate" Times column by Timothy Egan and marked up the text with red editor's notes.
"Thanks for sharing your first draft," Tovar wrote in a faux message to Egan. "Below are a few thoughts to ensure something inaccurate doesn't get published."
Wal-Mart sent a memo about Tovar's departure to its US leadership on September 12, without elaborating on his reasons for leaving. Tovar's college record didn't come up in a separate farewell email that he distributed to media.
"We all know the first rule of journalism is 'don't bury the lead' so here goes: after eight amazing years, I've decided to leave Wal-Mart at the end of the month," Tovar said in the message. "I have loved every second of every minute I've been with the company and I don't have enough room in this email to give justice to the life-changing experience of working for the world's largest retailer."
Tovar didn't say where he's headed next, and a replacement at Wal-Mart hasn't yet been named. The company is searching externally for candidates, according to the person familiar with the matter.
In an email to Bloomberg, Tovar said that now seemed like the right time to "start a new adventure."
"As a person from the Northeast, I never thought I'd take a job in Arkansas and then stay here for eight years," he said. "It's been an amazing experience and I'll definitely miss it."
