What is a Christian school?

[Kenny同志]

In what way is it Christian? Does it mean the school is founded by a Christian organisation or something?

And is an athletic director a teacher or a school officer?

Many thanks in advance for your explanation.

You may find the Wikipedia article useful... my understanding is that, whatever the founding and admin scheme, such schools offer religious subjects in addition to ordinary subjects. (The Christian viewpoint may or may not leech into the teaching of other subjects).

There may be additional things like having resident priests, part or all of the staff being priests or monks/nuns, arranging the day to integrate prayer or services...

(I once knew a girl who attended a Catholic school. In addition to normal classes and religious education, they would attend Mass every morning before class. This is a bit more than the average "Christian private school" in France.)

Thank you, edelweis. I forgot wikipedia.

I would think the athletic director is an administrator position. The person might at one point have been a teacher, but I think that is not relevant.

What is a Christian school?

Perhaps off-topic to your question, but part of this question is why parents would send their kids to a Christian school (or religious school in general), which is not really addressed in the wikipedia article. At least around here, there are three common reasons.

1. The instruction is perceived to be better than at public schools
   
2. The parents do not like the current culture in public schools (too sexualized, not safe enough, etc)
   
3. The parents want their children to have more religion in their lives / instruction
   

There are of course other reasons, but I think these are the big three.

Thank you very much for the addtional information, Jbradfor.

Or, where I come from:

4. Public schools are not allowed to refuse any children, but christian and catholic schools can refuse students who don't subscribe to their faith, which includes Muslim/immigrant kids. Christian and catholic schools may therefore be more 'white' and have less children of disadvantaged backgrounds. Some parents prefer christian or catholic schools for these reasons.

Many aspects of what a christian school is depend on which country the school is in. Different countries have different public school systems and different rules on christian schools. If this school is of some relevance in the thing you're translating, you might want to look into it in more detail.
