If the school has a specific supply list, I recommend you contact the school directly to obtain it. Using the info you provided, I wasn't able to locate their page in SchoolFinder, but did find this listing of Covington, Louisiana high schools (in case the name of the school has changed, or you meant one of these schools instead): http://www.education.com/schoolfinder/us/louisiana/covington/high/
I'm also including a link below to some additional resources you may find helpful to ease the back to school transition for your family. I hope you and your child (or children) have a great school year!
Hi, I found a long time ago that the schools usually give the supply list to stores like Office Depot, Staples, Walmart, and others. If you have one of these close to you, you might call and ask if they have the list for your school. Other than that you can check with other parents in the neighborhood for the list for your child's grade. The last resort is wait until school starts and the teacher will give your child a list of what they need. I know kinda late for the big back to school sales but at least you will get the correct and usable items from this list.
