Question: In lesson plan, we can see two items; one is 'Registration Number' and the other is 'Identity Number.' What is the difference between them. -- Two or three applcants for teaching at school will come and start teaching for demonstration for about 10 minutes. --

Answer 1

I'm not sure.

Registration number might be referring to the number given to each applicant as he or she applies for the job.

Identity number might be a permanent number assigned to each person, no matter what he or she applies for.

But ... I'm not really sure.
