Yes, it is he.
I'm not sure Calig.
For a start, he is Canadian so obviously looking at it from perspective of whatever they do over there I would imagine.
At this stage, I am familiar with its use with kids under 10, a lot of whom have SEN (althoguh his products not specifically designed for this group).
As I sadi, I'm not a teacher, so don't have in-depth knowledge of syllabus.
