THE SCORING GUIDE
SCORE 
DESCRIPTION 
4 
Outstanding: Solution includes 4 of the following 5 criteria

3 
Very good: Solution includes criteria items 1, 2 and 3 above. The solution does not violate any problem limit and follows all instructions. 
2 
Anything less than a 3 which still addresses the problem. A response which just guesses at the answer with no organized problem approach would be a level 2 response. 
1 
An incomplete, offtask, or blank response or a response which violates the problem definition or did not follow instructions, or shows that the team did not understand the problem.
