Unhappy Parent

I went to Ebony park primary school and spoke to the Class teacher (Mrs Shika) and she failed to assist me, instead she was rude and unprofessional. The issue is my son’s report indicates that he was doing excellent throughout the year however he was not nominated as one of the leaners who qualifies to get a certificate for the best performer or best consistent Leaner. I went to the school to ask the teacher why my son didn’t qualify and how he can improve to qualify for the certificate but I was advised that I am still young and she’s got a huge amount of number of leaner’s in class and can’t give all of them certificates. As I parent, I need to know why my son didn’t qualify for the certificate and I need to see the results that confirms that he didn’t qualify for the certificate because the report clearly confirms that he qualifies. The fact that I am a young Parent doesn’t block me to go to school when I have concerns regarding my son’s performance.
