Certifications for HCIA (Huawei Certified ICT Associate) are valid for three years. This means that your certification will remain valid for three years after obtaining HCIA certification. However, please note that the validity period of certificates may change due to Huawei's policies. To ensure that you get the most accurate and up-to-date information, please refer to Huawei's official website or check with the Huawei Certification Center. They will provide you with the latest certification policies and related information. In addition, even if the HCIA certificate expires after three years, the knowledge and skills you have gained are still valuable. Before the expiration date, you can choose to take a higher-level certification, such as HCIP (Huawei Certified ICT Professional) or HCIE (Huawei Certified ICT Expert), to further enhance your technical skills and career development!
