Ms. Do Minh Chau (Vinh Long) has been teaching English at the English center since June 2020 and has been continuously paid for compulsory social insurance from September 2020 to June 2023. In July 2023, she was recruited as a civil servant at a public secondary school and has been teaching until now.
Ms. Chau asked, is she allowed to accumulate teaching time at the center to calculate teacher seniority? By October 2025, has she had enough 5 years to consider teacher seniority?
Regarding this issue, the Ministry of Education and Training answers as follows:
The seniority allowance regime for teachers is implemented according to the provisions of Decree No. 77/2021/ND-CP dated August 1, 2021 of the Government. Accordingly, the time used as a basis for calculating seniority allowance for teachers is determined as the total time teachers directly participate in teaching, educating and have compulsory social insurance contributions at public or non-public educational institutions according to the provisions of law.

In case Ms. Do Minh Chau has participated in teaching at the English center and has paid compulsory social insurance from September 2020 to the end of June 2023, if the English center is a non-public educational institution established and operating legally, then this period is accumulated to serve as the basis for calculating seniority allowances for teachers; the teaching time before participating in compulsory social insurance is not counted.
From July 2023 to now, she is an official, directly teaching at a public secondary school and has participated in compulsory social insurance contributions, so this time continues to be included in the seniority allowance period for teachers.
Thus, from the time of being appointed to the professional title of secondary school teacher, not counting probationary time, when she has 5 years (60 months) of compulsory social insurance contributions, she is eligible to be calculated for seniority allowance for teachers according to regulations.
