Why do nursing students drop out of EIT (Eastern Institute of Technology) Hawke's Bay?

What is the reason for big nursing students  drop out of EIT in 2013?  Many of the nursing students who dropped out said that their  lecturers do not have a trust in them. It appears that the lecturers questioned student's hygiene in order to humiliate students, and set them to fail (OSH Ocuppational Safety and Health).  So many nursing students fail to graduate. It is not good.
