The number of junior classes with more than 30 pupils in Welsh schools has more than quadrupled in the past five years.
The official government figures were unearthed by the Assembly’s research service after a request by Plaid Cymru’s shadow education secretary Llyr Gruffydd.
In addition, infant classes in 11 schools throughout Wales were also over 30 pupils, despite the Labour Welsh Government making this unlawful under the Schools Admissions (Infant Class Sizes) Wales Regulations 2013. This applies to infant classes only – Reception, Year 1 and 2.
The statistics reveal a growing problem with large class sizes generally – the average class size in Wales is now 25.6 pupils compared with 25.1 five years ago – a 2% rise.
But there are critical problems in a growing number of primary schools where the number of classes with more than 30 pupils in years 3-6 has gone up from 44 to 181 in the past five years. This means a single teacher is in charge of more than 30 pupils. It does not include classes with ‘statutory exceptions’.
Llyr Gruffydd AM said, “This is a disturbing trend that is affecting more and more pupils in Wales. One in seven children in junior schools in Wales are being taught in classes of more than 30 if we include the ‘excepted’ pupils.
“The education secretary is breaking her own government’s legal regulations in a small number of schools and her stated policy of reducing class sizes is just not happening. On the contrary, the average size of primary school classes is increasing, placing greater pressure on teachers.
“This Labour Government is failing to address growing class sizes, it’s breaking its own rules and is putting growing numbers of teachers under greater pressure. Children, their parents and teaching professionals deserve much more than empty promises that are being broken on a daily basis in our schools.”
Mr Gruffydd added that it was pointless and dangerous to announce targets for schools in terms of class sizes without also ensuring those schools had enough funding to pay for the teachers needed,
“Schools are down to the bare bones in terms of reserves and pay rises being announced with no details of how they will be funded are hugely worrying for school governors and head teachers. There’s little point in making up regulations without the funding in place to make them happen.
“There is a wider point too that Plaid Cymru has been emphasising for some time that we need to make teaching an attractive profession to bring in new talent, by ensuring that pay and conditions match other similar professions.”
