The licensed practical nursing program at Vinal Technical High School in Middletown is preparing to close because too few graduates have been passing the LPN licensing exam. The state Board of Examiners for Nursing voted 5 to 1 on April 6 to recommend to Dr. Raul Pino, commissioner of the state Department of Public Health, that the program be closed immediately. The program has been in jeopardy since last fall because fewer than the required 80 percent of students have been passing the exam on the first try after graduation. Nursing board member Mary Brown voted against the closure, according to draft minutes of the meeting. Earlier in the meeting, she had proposed delaying the closure to let the current class graduate in January 2017 and take the licensing exam, but the rest of the board voted against her motion, the minutes said.
