The 2012–15 report was the first of its kind as it focused on the position of the Welsh language in the period between establishing the Commissioner’s office in 2012 and the end of 2015.
Adroddiad 2012–15 oedd y cyntaf o’i fath wrth iddo roi sylw i sefyllfa’r Gymraeg yn y cyfnod rhwng sefydlu swyddfa’r Comisiynydd yn 2012 a diwedd 2015.
