School is more of a cult then a school. If a kid sneezes they will send behavior sheet. Teachers are never wrong, and parents kept in the dark about everything. If the principle doesnt like you, ready to see it taken out on your kids. Uniforms cost a lot, and socks better be the right color and length. Your kid shows a ankle, you'll get a behavioral sheet. RUN far away as fast you can from this school! Close Quote

Challenge Charter School is an amazing place to work! Challenge is full of such kindhearted people that are passionate about kids and education. I have never worked for more warm or compassionate people. If you work at Challenge you work for a family and will become an extension of that and the Millers share that same welcoming nature with all the students that come each day. Challenge also has an amazing curriculum every time I learn more about it and the hands on learning I wish I had the privilege of attending this school growing up. GO EAGLES!! Close Quote

My daughter has been going to Challenge Charter since kindergarden and the year will be in the third grade. I have nothing but great things to say about everyone from the founders, the principle, the front office staff and most important the great group of nothing but top notch teachers that they have on staff. I had my reservation when my daughter first started do to all the issues I knew other charter schools had do to poor management and the only focus those choose had was personal financial gain. Not here. I mean like most schools now most of the after school activities cost extra. Like I see it if my daughter wants to be involved I have no problem paying the cost. Keep up the quality education and the high standards. Close Quote

Our daughter just started her second grade year. This will be her third year at Challenge. The school is just incredible, especially when you consider other schools here in the Phoenix Valley. It's simply amazing.

My biggest complaint are the uniforms. Not that we have to use them, but the fact that we are only allowed to buy ridiculously expensive uniforms and that we're ONLY allowed to buy them from Dennis Uniform. The walmart and target uniforms are literally a quarter the cost. I'm positive the school is getting some sort of kickback for this and it's a big monetary strain on our family.

That aside, the school is still worth it. I am AMAZED at how advanced our daughter is getting with her reading, math and science. I would absolutely recommend this school. Close Quote
