None of the free courses can provide a new certificate on existing accounts. Certificates for the free courses do not expire.
The courses are not offered yearly. Certificates are issued once per account and do not expire. If a certificate with a different date is needed, please register for a new account at https://lung.training/register.
Facilitator courses (OAS, NOT, Kickin' Asthma, etc.) will have new versions every two years before your certification expires. For example, the latest Open Airways For Schools version became available in 2022.
