Maybe from degree? I think most farmers would have a generic one. I don't think it is tailored individually for non-scholars.
Anyway, i think the masters point is quite true in civil service - helps in long run progression and development, but not so at the start.
I have a ex-teacher who did a
MOE Overseas TS, and he didn't do a masters for his subject because he wanted to 'teach' quickly. Fast forward 7 years, he did a HQ stint and is now a HOD of his department.
Another one of my friends who has a Masters from one of world top unis in his subject, told me that
NIE salary was the same as those without - he is a Teaching Local + Overseas PG scholar. I think the Ministry encourage overseas scholars to do a masters so it will help them in their long-term career progression.
