hi all (esp ROs)

i'm a GEO 4 officer and here is my career history. i'm a guy, degree from NUS, 2nd class upper.

Jun 2014: graduated NIE.
2014 grade: C+
Oct 2015: GEO3
2015 grade: C
2016 grade: B
2017 grade: B
Apr 2018: GEO4
2018 grade: B
2019 grade: B

end-2019, got a mandatory posting to hq. started this year. last yr i found out by accident from my previous sch that my CEP is SEO1. i have nv held a KP position before. was a little disappointed tbh.

just wondering:
- at my current stage of career, is it likely that my CEP will be raised further?
- when can i reasonably expect a promotion to GEO5 if my CEP is not raised?

i'm just thinking of all of this because i think i'm an okay performer, but so far not much luck career-wise. bosses are okay with me but no principal/leader has really paid attention to me at work. thinking that once the economy improves, i'll seek greener pastures but i also enjoy the work of a teacher.

appreciate any advice. tks!
