For CEC it should be skilled experience, that is, those considered NOC 0, A or B
How do you now?
Look at the first and/or second digit of the noc:
0.-All the codes that start with a '0' are NOC 0 Ex: 0XXX
A.-All the codes that have '1' as their second digit come under NOC A. Ex: X1XX
B.-All the codes that have '2'or '3' as their second digit come under NOC B. Ex: X2XX or X3XX
the IELTS score you need depends on wich noc you have
if noc 0 or A you need 6 in all sections of the test a little short on writing 5.5
if noc B you are good
