Would you tell me what is the meaning of this sentence? Thank you! A statement will also be required if you have been registered with the NZ Teachers Council before and have not taught since the last application. I cannot understand this sentence. Would you tell me the meaning of it, especially "before and have not taught since the last application." In addition, I have got another questions about this sentence. "if you have been registered with" why it uses present perfect here? Thank you so much!
