The design looks phenomenal, but I think the clarity could use some work, not sure if that's up for discussion... but here are my thoughts on the actual presentation / construction of the questions:
Under "Basics"
Do they need to be open-ended? (i.e. would it be better to have age ranges and "circle one" instead of "How old are you?"
You might add a frequency of attendance... weekly, bi-weekly, once a month, less...
Under "Ministry Experience"
I love the layout, but is it too much work / confusing?
I think most people would get that for the two questions, the numbers for the rating relate to their list, but that might not be readily apparent.
Is there a way to combine the response and the rating of each?
What does the number scale represent?
Is 1 or 10 better?
If I love the worship and sermon, but the service is too long, how should that be quantified?
What if the questions were open-ended here (along with combined as above)? Like: "What ministry are you involved in? What is going really well / something that ministry does well? What is something that could be better?" (That's three questions... but that might get you more of the answers you're looking for)
Under "Outreach"
What qualifiers are you using for determining "effectiveness" in outreach?
Great outreach could be converting people each week to one person, and feeding the homeless to another.
It asks how well you are "reaching people" in the church, community, and the world; but what would that mean?
