Feedback loop to the parents is important. And also walking the talk. Many centers say they do this and that in their curriculum but it is seldom fully delivered and yet parents pay the fees for what they were promised for the kids!
Not just that, the food served is also impt. I see some centers serving hot dogs and luncheon meat. Gawd.. The salt content can kill! Also some even avoid serving green vegetables but the menu I was given says that they serve spinach!
Bottomline, deliver what you promise when you set yours up.
