@Jellycatspyjamas I understand that - but the way to tackle this is to recognise that much of the problem is systemic and multi-faceted.
I believe that state-funded vocational and alternative academic routes should be available until 21, for Level 3 qualifications (ie including BTechs, T levels, apprenticeships) with funding for families and colleges/6th forms to support children who fall of the GCSEat16/Alevels at18 conveyor belt. Kids often fail for multiple reasons: ND/dyslexia that has gone undiagnosed, experiencing social deprivation, lack of jobs/dying local economy, lack of support in the home (for whatever reason: parents may have had undiagnosed SEN and been failed by that system themselves, have MH issues, be single parents struggling with childrearing and working etc).
The whole system needs adapting to allow for different learning styles, needs and later development - especially as we now know that most adults are not cognitively/neurologically mature until closer to 23, and developmental pathways vary alot depending on facts such as age of onset of puberty etc. the one size fits all education model that we have isn’t working and if we want to address youth unemployment and mental health, get them into fulfilling work as young adults, we need to do more than just gear it to the local job market.
We need more apprenticeships - but these also need funding and support if you want companies and small/sole-traders (builders, plumbers, plasterers, hairdressers, independent hospitality providers etc) to take on young people to train and mentor - and less red tape around younger employees. There are fewer and fewer Saturday jobs and opportunities for young people to get that first exposure to the working world and start building a CV - the govt could sponsor Saturday job schemes or give tax deductions to make this worthwhile for a company/traders.
It needs far more creativity than he is proposing if we want to fix the growing NEET issue.
