WITH regard to the recent Programme for International Student Assessment (PISA), which states that Scotland’s pupils are lagging further behind pupils in numerous other countries, the usual SNP excuse is that it is not their fault. This failure, according to Education Secretary Jenny Gilruth, is down to Covid, which is the usual scapegoat these days. I wonder how our once enviable education system managed to carry on during two world wars and continued that success until the SNP was installed? Then again, Covid has been blamed for many things – which makes a change from the SNP’s default setting of blaming everything on Westminster. It may explain the SNP’s history of fail, fail, fail and could do better. But then they couldn’t do any worse… could they? Peter Mackie, Sauchie, Clackmannanshire.
