English medium streams will be phased out in state schools in Gwynedd.

The council plans to make Welsh the principal language of education in every school it administers.

The authority is planning the first major review of its Welsh language education policy in more than four decades.

The Draft Revised Education Language Policy will come before the council’s Education and Economy Scrutiny Committee meeting on Thursday, 10 April.

The shake-up will see Welsh becoming the significant language used to teach children in the county’s schools.

The proposed change will affect three schools: Ysgol Friars, Bangor, Ysgol Uwchradd Tywyn and Our Lady’s Catholic primary School in Bangor.

The Category 3T schools or “schools in transition”, are moving towards full Welsh medium provision.

Welsh is already the predominant medium in the rest of the county’s 90 plus educational establishments. They are considered to be in the Welsh Government’s Category 3 – schools that already offer a significant amount of Welsh medium provision, with Welsh being the main language of internal communication.

Children who move to the county from non-Welsh speaking areas will be referred to attend Gwynedd’s Immersion Education System.

The main changes will see all pre-school education settings teaching through the medium of Welsh, all pupils in the Foundation Phase until the end of Year 2 being taught and assessed through the medium of Welsh, and schools providing opportunities for pupils to use the Welsh language regularly, inside and outside the classroom, in a curricular and extra-curricular manner.

From Year 3 onwards, at least 80 per cent of the pupils’ educational activities (both curricular and extra-curricular) will be in Welsh.

Pupils’ grasp of Welsh will continue to be developed, giving attention to the development of their skills in both languages. From Year 3 onwards, English will be introduced as a subject and cross-curricular learning medium.

In secondary schools Welsh will be the main language of education for all pupils up to 16 years old.

Pupils’ grasp of Welsh will continue to be developed, giving attention to the development of their skills in both languages. English will continue to be introduced as a subject and learning medium of some cross-curricular elements.

Schools are expected to ensure that all pupils (Years 2-9) who are latecomers and new Welsh speakers are referred to attend Gwynedd’s Immersion Education System.

Children and young people with additional learning needs (ALN) will receive equal linguistic opportunities in accordance with the policy.

The council says the new policy is in line with Welsh Government’s Welsh 2050: A Million Welsh Speakers’ strategy.

The proposed changes will have to be scrutinised and debated in the council’s cabinet and full council. A public consultation will also have to be held.

The council said in a report published on Wednesday, 2 April, that: “This policy is an attempt to set Gwynedd’s ambition to ensure that the county’s children and young people grow up to be proficient users of the Welsh language and develop bilingual or multilingual skills within our education system.”
