Gillian Keegan, current Education Secretary (you might not know this as there have been a few recently) was just interviewed by Sophy Ridge and said that parents shouldn't be worried about school funding.
School funding has been below 2010 per pupil levels for 13 years now. This has resulted in redundancies of TAs, support staff and teachers. It has resulted in subject choices being cut at GCSE and A-level. It has resulted in the school estate crumbling to the point where some school buildings are officially at 'imminent' risk of collapse, and there have been injuries to children and school staff where ceilings have fallen in.
Headteachers had to make further cuts last summer due to a late-announced unfunded teacher pay rise for September.
There is a shortage of TAs as schools can't hire due to being unable to afford competitive pay levels and TAs are choosing to work in supermarkets instead of schools.
There is a shortage of exam invigilators, again partly due to uncompetitive pay, and the government has been forced to relax ratios to allow exams to go ahead.
There is a shortage of teachers and now this year and next there is a devastating shortage of people training to be teachers, for various reasons including workload and lack of flexible working, but also uncompetitive pay.
Schools are also having to prop up the gaps left by the collapse of local services such as CAMHS and SEN support services who are now largely inaccessible.
We had a pandemic which adversely affected the education of children, and yet school funding levels remain below that of 2010.
How can parents possibly not be concerned about school funding?
