学校 (xué xiào) literally means 'study institution' — 学 (xué) means 'to study' or 'learning', and 校 (xiào) means 'institution', 'campus', or 'school' in the sense of an organized place for education. Together, they form the standard, neutral term for any formal educational institution, from elementary schools to universities. It’s used broadly across all levels of education and is appropriate in both spoken and written Chinese.

This word appears frequently in daily life: students talk about going to school, parents discuss school events, and official documents refer to school policies or enrollment. Unlike more specific terms like 小学 (xiǎo xué, 'elementary school') or 大学 (dà xué, 'university'), 学校 is generic and context-dependent — its exact level is usually clarified by modifiers or context. It carries no strong emotional connotation and is neither formal nor colloquial, making it highly versatile and safe for learners to use.
