Cyn y pandemig, roedd safonau llythrennedd a rhifedd yng Nghymru wedi gwella'n fawr, diolch i waith caled ein gweithlu addysgu. Yn 2018, Cymru oedd yr unig wlad yn y DU i wella ym mhob un o'r tri maes (mathemateg, darllen a gwyddoniaeth). Mae'n amlwg bod y pandemig wedi amharu ar y cynnydd hwn.
Before the pandemic, we saw a strong improvement in literacy and numeracy standards in Wales, thanks to the hard work of our teaching workforce. In 2018, Wales was the only country in the UK to improve in all three domains (Maths, Reading and Science). It is clear that the pandemic has derailed this improvement.
