Our internal modelling estimates for extending the Level 3 entitlement to adults aged 25-29 is around £20 million over the CSR period (i.e. from 2008/09 to 2010/11) in respect of tuition fees. Our estimate of extending it to adults aged 25-34 is around £40 million over the same period. This is probably near the bottom end of likely costs: were participation to increase as a result of the entitlement, costs could be much greater.
We currently have no plans to extend the Level 3 entitlement beyond its current age-range of 19-24.
