***NOT A TEACHER***uncle 123, good afternoon. English is very difficult, but I have good news. Your question has a very EASY answer. Just remember that after the auxiliary verbs such as "do," "does," "did," and after so-called modals (will, should, may, must, etc.) you ALWAYS ( no exceptions!) use the base form of the verb (base form = the form listed in the dictionary when you are looking for a word). So: When DID you JOIN? It is a question using the simple past. (P.S. Present Perfect would be: Have you joined the school?) Have a nice day!

I think The Parser has already written very good information.

As an addition:
"When did you join the school?" = Simple Past

Whenever it's a question or a negative sentence you will need a "do".
I did not join the school.
Did you join the school?
Did you not join the school?
When it's a positive sentence you do not need the "do".
I joined the school last year.
You can write:
I did join the school last year.
but it's not necessary.
(It's more to emphasize the sentence.)
Example:
Person 1: You did not join the school, did you?
Person 2: Sure! I did join the school!

A very important fact:
If you ask who did something, you don't need the "do":
Who joined the school?
Who enjoyed the party last night?
Who watched this movie?

If you have any other questions just ask.

Cheers!

To add to what the others have said, in English, generally the first verb of a verb phrase is the tensed verb.

So, yes, the sentence is simple past, but it is the 'do' that is given the past tensing - did. This means that the 'join' doesn't need to be tensed, since the fact the sentence is past is indicated by the 'do' as 'did'.

No it isn't present perfect. Present perfect is formed using the auxilliary "have" in the present tense plus the past participle of the main verb. It wouldn't be appropriate in your sentence.
