@Teflon @1993 not sure where your information is coming from, but CEP is definitely not failing (at least in respect of the stated aims of the programme).
LIBOR meets the core costs of the programme (which is joint DfE/MOD - but with the bulk of the funds spent by MOD as the delivery agent) but post-2020 the sustainment costs will fall to MOD; unless some other arrangements are negotiated. The costs are not in the establishment of the units themselves as such, but in the enabling/support structures, esp. Personnel (a mixture of contractors, Crown Servants, and FTRS). Having said all that, if you read the section in DYER re. the respective costs of the CFs per head - the CCF is the next cheapest option after SCC; and the delivery model is directed and governed by MOD.
The goal of 500 in-school units (inc. "linked Detatchments" in Scotland) by Mar 2020 will be achieved. Take up varies region to region (thus my point in a previous post about it being demand driven); but I don't think there will be any great difficultly in hitting the target.
The bigger question then is - in areas where the community CFs are failing (and there are plenty of them), could the CCF delivery model ensure continuity of CF presence in an area, eg remote/rural; in a cheaper fashion? The ACF in particular is extremely expensive - relatively - in its current form; and many community CF units hover around the 20-30 cadets mark. Are they delivering effect and VFM?
