If you ignore fancy title like "lecturer" in poly and ITE, the pay progress is about same as MOE teachers (non-mgt) in secondary/JC schools.

Just like normal teachers, unless you are in the management track as a HOD/VP equivalent in the poly/ITE, 7-8k is consider near career max and only those in their late 40s or early 50s get it. Most lecturers in poly/ITE are 3.5-5k and senior lecturers 4-6k, only very experienced old) ones get 7k+.

My advice for all those young 30+ PME in pte sector, please only join if you are truly passionate about teaching. If your intention is to get the same pay & bonus as before while relax one corner work life balance then you are just wasting everybody (inc yours) time.
