Being a Mandarin teacher

Recently, I  was preparing to study how to be a good Mandarin teacher. There are many certificates relating to the course, such as ICA, IPA, IMCPI, ISCLP, ICTA, IATCSOL / TCSOL.  I want to know  which certificate has more value than others.

I work on weekdays, but I want to earn extra  money as a Mandarin teacher part-time. I want to ask any foreigners here who want to learn Chinese: What kind of certificates  do you need? What would you expect from your teacher? What type of  teacher/ certificate would you trust?
