Seattle Prep will undeniably prepare you for college with 90 minute classes, frequent essays/presentations, and a block schedule. Students are highly motivated and involved, and teachers are available to support you. The academics are no joke and time management skills must be strong in order to find success.

Seattle Prep has given me an opportunity to grow and challenge myself, every day it continues to push me past what I think are my limits into new territory. But with all of the opportunities Seattle Prep provides there are draw back, the weight of the expectations does not always come with the support and the environment while rigorous can be cutthroat and is not very forgiving.

I would like to see much action taken to help reduce students stress and minimize the competitive culture of the school. It would also be good to see a boost in school spirit overall.

Worst school I have ever attended. The students that go here are bullies and are rich awful people. I would avoid this school at all costs. Send your kid to your assigned public school instead. This is an awful school.

The students th...
