I have a very close friend who joined the profession in 2005 as a mid career entrant.His pay then was $3.5k per month.Now he is drawing slightly close to $6k monthly.Certainly not the best in the world but he can make ends meet.But there is a ceiling in terms of pay unless you are promoted to leadership positions which will elevate the ceiling higher.But bear in mind that the ceiling is well below $10k per month even for heads of department.Do consider carefully and talk to people you know who are in the teaching profession before making a decision.
