The Center collects evaluative data from participants, users, attendees, etc. to measure how effective specific events, services, and projects were.  It also calculates return-on-investment (ROI) to measure the financial value when contrasted with a for-profit event, service, or project that meets comparable criteria, with at least three samples used to calculate an average “cost” per-person or service or project cost in the market place.   The basic formula the Center uses is expenses divided by per-person or overall service or project cost.  This is then compared to what it would cost if profit was a consideration in the overall revenue generated.  In-kind donations are also factored into the overall quality of an event, service or product.  Evaluative data is also a factor in whether or not the project, service, etc.  was of value to the “customer” and did it create a change in thoughts or future actions taken by the customer.
