After the expiration of the "three supports and one support", people are admitted to institutions without using three identities. Can they still use three identities to test civil servants?

The first is the question of institutions applying for civil servants.

You are already a staff member of a public institution, that is, you belong to the establishment. It is clearly stipulated in the recruitment announcement of civil servants that on-the-job civil servants, public officials (including civil servants and public officials during the probation period) and staff of public institutions during the probation period (listed recruiters) are not allowed to apply for civil servants.

If you want to take the civil service exam, you need to quit your job in a public institution before you can take the civil service exam.

Secondly, the question of applying for the "three-in-one" status of civil servants.

Generally, within three years after the end of the service period of "three supports and one support", you can apply for civil servants as "three supports and one support". Those who have served for more than three years cannot apply for civil servants as "three supports and one support".

I hope the above answers can help you.
