It's a question asking for a description of a school, possibly in terms of:
* Atmosphere: Is it lively, quiet, friendly, etc.?
* Structure: Is it big or small, modern or traditional?
* Curriculum: What kind of subjects are taught?
* Teachers: Are they strict or lenient, experienced or new?
* Students: Are they well-behaved, diverse, etc.?
The context will determine the specific aspects of the school being asked about.
