I don't know how any Conservative can claim to be serious about education.
Spending on school sixth forms & colleges -
Since 2010–11, there has been a decline in per-student spending across all types of institutions. Between 2010–11 and 2019–20, spending per student fell by 14% in colleges and 28% in school sixth forms. For colleges, this left spending per student at around the level it was in 2004–05, while spending per student in sixth forms was lower than at any point since at least 2002.
Overall, per-pupil spending in 16–18 education is set to rise by 9% between 2021–22 and 2024–25. Yet even with the additional funding set out in recent spending reviews, college spending per pupil in 2024–25 will still be around 5% below 2010–11 levels, while school sixth-form spending per sixth-form pupil will be 22% below 2010–11 levels. Therefore, the additional funding for sixth forms and colleges will only partially reverse the cuts of the previous decade.
