There really is no specific criteria for a quality contribution. Any contribution that helps out the site of WikiAnswers, whether it be categorizing a question or minor editing a question, is considered good. Generally, however, a good quality contribution comes in the form of an answer. A good quality answer will usually be 2-3 sentences minimum and will be free from spelling or grammar errors (and hopefully false information!). That seems to be the consensus for a quality contribution, but as stated before, any contribution that helps out WikiAnswers is considered a good contribution. A good quality contribution is basically not a wasted contribution. For instance, categorizing and recategorizing the same question 10 times just to gain contribution points is not considered a "good quality contribution." However, categorizing that question properly, answering it with a well-informed answer (free from grammar and spelling mistakes), and adding a related link would count as 3 great quality contributions. Thus, any contribution that helps out WikiAnswers and is not "yes it is because i said so" as an answer, as an example, is a quality contribution.

You do not have to answer a certain amount of questions to upgrade your ranking on WikiAnswers. Any type of contribution will work to get you to the next rank. (Contribution types: messaging, editing, answering, or removing an answer, splitting and adding alternates, asking a question, and editing categories can get you contribution points. See the question "What are the various contributor levels on WikiAnswers" to see the next level you will become.
Any action you perform on WikiAnswers will generate a contribution of some kind. Whether the activity generates one or more points depends on the activity. Chatting, forum entries, and merging may not generate actual points, and the totals of your points could be adjusted by future guidelines. The point of wikianswers is not simply to generate points, although the points indicate your comparative interest and aid to the site.
Your total WikiAnswers contribution points are calculated as the sum of all of the contribution points you have earned. These include first answers, edits, organizational actions, questions asked, and community contributions. All of these points come under the heading of "Contributions" in your WikiAnswers profile. Trust points are slightly different. Contributors do not directly earn these points through their contributions; they are awarded trust points by other WikiAnswers users. Therefore, trust points are not counted as contributions, and do not add to the contribution points total in a WikiAnswers profile.
