Do the public schools have a website where we can get that same information?
Yes, usually in their annual report which is generally posted on the district website. Additionally, MEAP scores, if that is what you are interested, are generally published in the newspaper.
Edited to add: It is about time charter schools have to come across with some data. Now, let's make them take everyone who shows up, just like the public schools, instead of cherry picking the students they want to work with.
