The implementation status of problem–based learning （PBL） tutorial systems was surveyed in 2008, 2011, and 2012. The 2008 survey showed that the content of PBL tutorial systems differed greatly among universities.
  In response to a question in the 2011 survey of whether the PBL tutorial system would last for 5 years or more, more than 80% of universities agreed that the systems would likely last that long.
  In response to a question of whether PBL tutorial system had been changed around 2012, more than 80% universities said the system had not been unchanged. Furthermore, regarding the evaluation of tutors, the motivation of tutors as a whole did not increase. In the future, the implementation status might not be changed.
