SAN ANTONIO — A vocational school operating in Texas and Oklahoma has closed amid what administrators say was a federal dispute over inappropriately received student aid funds.

Career Point College President Larry Earle says the San Antonio-based school closed Sunday. The school, with about 1,400 students, also has campuses in Austin and Tulsa, Oklahoma.

Earle says school administrators discovered two months ago that three employees violated rules on student aid. Earle says the school reported the matter to the Department of Education and offered to repay the mishandled federal funds.

In a letter, the federal officials said about $4.6 million in federal funds was obtained improperly and required a letter of credit for more than $10 million for the school to continue.

The college offered medical, nursing, business, cosmetology and information technology courses.
