Hi Anthony - I'm afraid the best I can find is VIRTUE. That certainly means 'quality' in some senses, but wouldn't work very well in your context (i.e. Virtue Improvement Team sounds silly). It's a shame you're restricted to six letters, as there are plenty of other good synonyms.
Cheers,
P.S. Next time you're stuck for synonyms, you might want to try a word finder called WordWeb. It comes in a free version which is fine for everyday words like these.
This selection comes from an impressive vocabulary program I started playing around with a year or so ago. It's based on a huge dictionary of 150,000 words taken from all the 'big name' vocabulary courses and exams.
