A "conscientious effort"[1] must be made to consider the impact of the decision on the Welsh language. The threshold for “conscientious effort” depends on the circumstances and more must be done:
- in a sensitive or significant area in terms of the Welsh language
- as the number and/or impact of the possible effects on the Welsh language increases
- if there is a local policy or guideline (e.g. in the field of education or planning) requiring an assessment of possible effects on the Welsh language
It is more likely that a “conscientious effort” will be made if a wide range of impacts are considered.
It is not sufficient to include a series of factual, general statements about the Welsh language (e.g. number and % of Welsh speakers in the area, information about Welsh-medium schools, the body's expenditure on the Welsh language etc.). That is not equivalent to considering the possible effects of the specific decision in question on the Welsh language.
