They are/were due for another site visit this year according to the AVMA website, idk when that was supposed to happen. Unsure why they remained provisional after their site visit last year. There are many other standards schools have to meet besides the NAVLE pass rate.
"If a college granted Reasonable Assurance is making adequate progress in complying with the Standards, Provisional Accreditation may be granted to that college on the date that letters of acceptance (admission) are mailed to members of the initial class. When Provisional Accreditation is granted, interim reports are required at six-month intervals to monitor the program’s progress in complying with the Standards. In particular, changes in business or educational plans must be addressed in detail. Provisional Accreditation status may remain in effect no more than five years if the program complies with the necessary requirements. A program with Provisional Accreditation for five years or that does not provide continuing evidence that its program will comply with the Standards and its plan may be placed on Terminal Accreditation."
You could reach out to the school or AVMA to check in. I think this is the 5th year for LIU right?
