Many of us take speaking for granted. But what if the words in your head just won't come out? For over half a million people in Britain, a stutter affects their lives every single day.
Stammer School follows a cast of struggling stammerers as they enrol on an intensive four day course called the McGuire Programme.
The programme features Vicky Croft, who was a fluent speaker until she suffered a minor stroke last December, and Debbie Rasaki, a nursery nurse who has stammered since the age of 4. Vicky and Debbie are here today, along with Rich Whincup who was himself a chronic stammerer but is now a course leader on the McGuire Programme.
