1. Scope

This standard applies to the new design or renovation of vocational secondary school facilities within the national education system.

NOTES:

1) Vocational secondary schools are vocational education institutions within the national education system.

2) Vocational secondary schools are organized in public and private forms. Public vocational secondary schools include those under ministries and sectors; those under provinces and centrally-run cities. Private vocational secondary schools are established and invested in by social organizations, socio-professional organizations, economic organizations or individuals.

3) For schools with special requirements, when permitted by competent authorities, they can be designed according to specific design task requirements.
