During the last decades there has been a rapidly growing number of language OERs which are created and published online with the aim to be re-used, re-published and/or reshared by language educators within their communities. But how can we be sure that all these openly accessible language materials are of good, very good or high quality?

OERs quality is not guaranteed. That means that it is highly important to reassure their quality control, assurance and evaluation if we want an OER to be re-used by others. Language teachers have interchanging roles: either the role of the OER creators or the role of the OER end users. An OER of good quality is the one that will be possibly used by many or even by thousands of teachers. This is very important because by co-sharing quality language OERs, the teacher who is a language OER creator contributes to a wider language teachers’ community which saves time and effort in this way. This OER co-sharing process also promotes language teachers’ collaboration and creativity.
