In my country ,gender,age and socio-economic status has highly affected supervision.At the post graduate level,most of the students are working and it is common to find that the student’s earn more than their supervisors and this has brought some lack of respect towards education as a profession, and hence,affecting supervision negatively.
Age factor is another variable,whereby the supervisor may find the supervisee is advanced in age,with some expectations which may not be met.Further,aged students lack commitment to their research work and this delays completion
