Older teenagers face biggest funding cuts
Older teenagers have been the biggest losers as spending on sixth forms and further education has been "continually squeezed" for 25 years, says a report.
Spending on 16 to 18-year-olds has faced cuts too often while education spending overall has risen, says the Institute for Fiscal Studies.
However, government plans mean schools as a whole face "real-terms cuts for the first time in 20 years", it adds.
Ministers say they will protect further education until 2019-20 in cash terms.
According to the IFS, the last 30 years as a whole have seen increased spending per pupil for most age groups, and particularly for nursery age children.
But spending on 16 to 18 education has been "a notable exception".
