School Reviews
5 10/10/2025
The high school I attended in the far more affluent city of Mill Creek, Wa. named Henry M Jackson HS, did not hold a candle to Zillah HS. The teachers were far more passionate about what they were teaching, they encouraged independent thinking with frequent and stimulating group discussions on current events, ethics, the world, and anything relevant in the world at that time. They always went above and beyond to make sure I didn't get left behind in math class if I was struggling and always were available to talk and help in any way they could. You are not just a number at Zillah HS. I hope it is still as wonderful.
