I have to disagree. These lines are from the application form :
Your Work Experience
a) Identify, from the list below, the primary occupation and the corresponding four-digit 2011 National Occupational Classification (NOC) code that will be used to assess whether your application meets the minimum program requirements to be eligible for processing.
Occupation NOC
b) Starting with your current occupation, list your occupations within the 10 years preceding the date of your application. For each occupation, identify the dates of employment, your occupation, the appropriate four-digit 2011 NOC code, the number of years of continuous full-time or equivalent part-time experience, and a description of your main duties.
My co-applicant haa already got his PER which he stated 2 NOCs too. My ECAS status is "in progress" and my CC was already charged.
