Gradings are held at the end of each term and are an excellent way to track the students progress. Provided you have trained regularly (2 times per week) you should be fine to grade each term, although final approval must be given by the Sensei. Each new grade will see the student progress to a new coloured belt. It is a great system to keep them motivated and training hard.
