To clarify things and remove all ambiguity, here is how things happen:
We have to understand "Eligibility" and "CRS" score. Eligibility is program specific. Programs are under which an applicant applies and qualifies, like FSW, PNP, CEC etc. For FSW, the required points is 67 and the maximum an applicant can get is 100. For FSW see <

Now goes the CRS score, which is the overall score an applicant gents and is ranked in the pool. When an ITA is issued, the applicant has to ensure that he remains over the ITA cut-off. If the applicant falls under the ITA but off score, the application will be rejected. <

An applicant not only meet the minimum ITA score, the applicant also has to meet the program requirement. It is the combination of both the factors. This is why when many applicants make a profile, they get a message that they do not meet the program requirements, even though they may have a high CRS score. For the FSW, there are 6 factors that are taken into consideration and each have a minimum requirement. See the link above.
Now lets come to the NOC and work experience:
For the work experience under FSW, IRCC states:
The applicant must have accumulated at least one year of continuous full-time (or the equivalent in part-time) paid work experience in the occupation identified in their application for permanent residence as their primary occupation. In calculating this period of work experience, the occupation must be listed in skill type 0 (Managerial occupations), skill level A (Professional occupations) or skill level B (Technical occupations and skilled trades) of the National Occupational Classification (NOC) 2011 [R75(2)(a)].
The applicant’s skilled work experience must also
- have occurred within the ten years preceding the date of their application for permanent residence; and
- not be in an occupation that has been designated as a restricted occupation.
In addition, during that period of employment, the applicant must have
- performed the actions described in the lead statement for the occupation as set out in the occupational description of the NOC [R75(2)(b)]; and
- performed a substantial number of the main duties, including all of the essential duties, of the occupation as set out in the occupational description of the NOC [R75(2)(c)].
Note: The applicant does not need to demonstrate that they meet the “employment requirements” listed in the NOC occupational description.
A simple interpretation of this states that an applicant applying under the FSW has to have at least 1 year of continuous full-time (or the equivalent in part-time) paid work experience under the NOC they have selected.
An applicant can combine 2 or more than 2 NOCs for the work experience requirement, however, 1 year has to be in one NOC.
Now if an applicant has over 3 years of work experience, his CRS score for foreign work is maxed out (Canadian Language Benchmark Level [CLB] 7 or higher) - <http://www.cic.gc.ca/english/express-entry/grid-crs.asp>
However, for the FSW program eligibility the score is maxed out at 6 or more years at 15 points. http://www.cic.gc.ca/english/immigrate/skilled/apply-factors.asp
In conclusion, you only have to meet the program requirement, but keep your CRS score above the minimum ITA score of the round you were invited in. If IRCC does not consider one of your work experiences because you entered a wrong NOC code, see if you still meet the FSW program eligibility, and if it impacts your CRS score. If you meet the program eligibility and also have the CRS score over the cut off, you need not send a CSE. If you do send a CSE changing your NOC code, it will depend on the agent evaluating your application if he accepts it or not.
Even if your application is rejected, you can re-file.
Hope this helps!
