The skill code ranks the difficulty/skill level of a technique by using points. Some skills have been taught in grade 10 already, but is used in grade 12, e.g. measuring. These skills can only be awarded one point, as it is a not a grade 12 level skill.
You may therefore, add measuring under 'any other skill not mentioned' at the bottom of the list,and award one point to it. See attached skill code document.
Comments to improve on the skill code for 2009 will be welcomed.
