Correct NOC

[denapr]

My wife, who is the prime applicant in our case for Express entry, is working as a Primary school teacher (NOC 4032). She has over 13 years of experience. Her first job lasted for 2 years as a primary school teacher, however, her internal designation in the institute was Assistant Teacher (being relatively a fresher and the rank increases with number of years of experience) but her role was that of a Primary school teacher. Now, my question is whether she should declare her first job under NOC 4032 (Primary teacher) or 4413 (Elementary Assistant teacher). I thought of approaching the employer asking them to mention correctly the designation as Primary school teacher, however, they may not agree to give a different experience letter as it has been 11 years since she left the institute. Please help.
