How to work more effectively with mixed ability groups in a Training Environment

Choosing this area for action research was prompted during my own reflective practice from
delivering Training to Officers within the National Crime Agency. I based my decision on three things;
1) Its’ a topic that I am very interested in and confident to examine.
2) Its creative and allows me to consider new areas of interest
3) Its’ not too broad and the topic fits the scope of my paper by focusing on students working for the NCA.
