The BJA have put together a web site which provide details of the Kyu grade syllabus requirements. Some of the demonstrations are perhaps not perfect technically but it gives a clear idea of the techniques.
The site is at the link below. Choose the relevant grade from the bar at the top and you will see the required techniques. The division of techniques into 3 mon grades is for junior grades only, the senior kyu grade with one grade per belt includes all techniques.
