The problem I have with Estyn is, Wales opted out of OFSTED when their schools were being consistently graded as Failing or Needing Improvement. They introduce their own inspectorate and BANG they are suddenly all outstanding.
They have also now opted out of their PISA targets.
It smacks of "fingers in the ears going lalalalalalala- we are outstanding if we say we are"
I know it is not just down to the Welsh Language policy - but that does play a part.
English speaking parents will say "Yes they've picked it up well" and "they were fluent very quickly". The only thing anyone ever talks about in Welsh schools is the Welsh language (which they teach very well btw). Ask how well they teach maths, English, Science, Geography etc.
I now live overseas in a SE Asian country that has a similar attitude to its state education system - it has moved away from teaching in English to teaching in it's national language (which no one else speaks), despite the majority of parents wishing to keep the option of English medium, the persistent denials that their system is failing students, that they consider themselves outstanding, but all international ranking put them in the bottom 10 in the world (along with Peru, Qatar and Indonesia) Classes of 50+ and a hugely overworked, under resourced demoralised teaching profession, who get blamed for all the failings.
It has led to a mushrooming of "budget" private schools who teach in English - no frills, really basic, but the key is the English medium, and ordinary working parents go without to pay for them. I teach in one.
I'm getting off topic, but it's my favourite soapbox and I see so many parallels between Wales and where I am.
I'm not against Welsh Medium Schools, I am a product of one myself. But I am in favour of parental choice. Why won't some counties offer the choice? (Ynys Mon and Gwynedd - I'm looking at you!) Because they know the majority of parents would opt for English if the choice was there, even though most parents won't admit it openly because everything is lovely and we're all speaking Welsh. There is one school on Ynys Mon that is allowed to teach in English as it serves RAF Valley. It is massively oversubscribed.
I think all children should learn Welsh up to GCSE minimum. It is a beautiful language which is still relevant and useful if you live there. I'm ashamed to admit, since I have moved abroad the standard of my spoken Welsh has deteriorated, and I should find a way to work on it.
There was nothing wrong with the system I went through (Bi-lingual - parents choose Welsh or English stream)
The English stream was taught in English except for Welsh language and literature, taught to a high standard and most of them were near to bilingual by the time we sat O-level.
I'm showing my age now and will shut up.
