Hello, if you are looking for a Christian based program then noahsnet.com is great! I'm not sure how other programs work but this one filters by opening a new browser for the child and then cannot access anything that is wrong, I think you can change the levels but I know there is a very strong filter. And then you can add or remove websites if you want. There is bible trivia and a lot of fun activities on it. I hope you find what works, God bless!
