What is the full name of PTA?

At present, there are several corresponding English:

Xinjiang Production and Construction Examination Information Network of Corps Personnel Examination Bureau

Qinghai personnel examination information network

Shanghai Vocational Testing Bureau Shanghai Vocational Ability Examination Institute

Hebei Personnel Examination Bureau Hebei Personnel Examination Network

I think it's better to use a professional one. Personnel examination networks or institutions generally have two functions. 1. Used for vocational qualification (professional title) examination, 2. Used for government or institution recruitment examination. Personnel refers to "all staff" or "personnel department". The professional adjective "major, major" and the noun is "major".

The test only needs to use the prototype. Table noun, "exam".

Authority is single. As the case may be, an institution uses the singular.
