RevTrak, the online payment system for New Trier High School, will be unavailable on Saturday, June 17, as it gets a new look that will make it easier for you to pay from your mobile device. The redesigned website will have the same payment categories, but in a more user-friendly home page. You also can visit from any mobile browser and make payments right from your smartphone or tablet! The attached Web Store and Customer Account Guides include more information about how to make payments through RevTrak. You will find the New Trier web store at the top of any page on our website, www.newtrier.k12.il.us . Just click "Payments."
