The 2.4-year validity period does not refer to soft research, but refers to the project manager certificate after applying for successful system integration project manager, and the validity period of soft research is 3 years;
3. The validity period from 4 years is the time available on the website of the Ministry of Industry and Information Technology after your first successful application;
4. The validity period of the soft test certificate (system integration project management engineer) is 3 years, which means continuing education is needed within 3 years. However, as mentioned in the first point, the Ministry of Industry and Information Technology does not require the expired soft exam to apply for a project manager, so anyone who has passed the soft exam can apply for a project manager. System integration project manager certificate is valid for 4 years, that is to say, continuing education will be done within 4 years. Both certificates have the saying of continuing education, so be sure to read the name of the certificate described clearly.
