many thanks, all who replied

I'm 14 months into my Work Programme referral and I'm wondering what happens afterwards. I'm pretty sure I remember being told that the referral was for 24 months (Ixion). I'm a 54 year old male and I've had lots of interviews and been diligent about going into their offices a couple of times a week, work diary properly typed out and verifiable. But now I'm nervous about what happens afterwards? Do I go on to a mandatory work scheme? Does anyone know? Any guidance greatly appreciated-
