However, extensive VET investment has not yet yielded changes in the proportion of students undertaking upper secondary VET, and with enrolment rates at 27% in 2015-2016, the 2017 is unlikely to be met. According to OECD (2017[47]), the lack of continuity in implementation of all types of externally-supported large-scale VET projects beyond the initial funding cycle is seen by officials as compromising their success. Projects have a fixed length of generally no more than five years, which is a short period to set up proper institutional mechanisms.
