GreatSchools Rating
Parent Rating Average
The Byron CUSD is well funded via taxes paid from the local nuclear plant. This school offers a private school feel (setting) with the price of a public school.The CUSD staff is top notch - they CARE about their students. They staff (from the Superintendent down) puts the needs of the students first. Our daughter began her time at Byron as a 3.5 year old pre-K student. After having a liver transplant, she was behind in all areas - education, physical, etc. We credit staff at Byron with helping us to make sure that our daughter achieved whatever it was that she wanted to. She is now a junior in college and majoring in education. She wants to give back to the vocation of education and to the educators that never gave up on her and helped her to set her sights high.
