Most workplace-recognized first aid certificates are valid for about 3 years , but some CPR-focused certifications are only recognized for about 1 year , and exact rules depend on your country, provider, and employer requirements. Always check the issue and expiry dates printed on your actual certificate and confirm with your training provider or employer, because local regulations (for example in parts of Australia or Canada) and workplace policies can require more frequent renewals even if the card itself looks “in date.”
