The Trainer Resources Portal has been developed to support the WMO Competency Requirements for Education and Training Providers. The portal contains all resources used in the earlier WMO Online Course for Trainers, plus additional resources when available. In most cases, the resources are being offered as open educational resources (OER), and can be used and adapted for other initiatives of for training by any institution or individual. Most are offered under Creative Commons License that allows for reuse as long as World Meteorological Organization (or the stated owner) is attributes as the source, and that any adaptions will also be shared freely under the same license.
