The school may require the physical form be uploaded into AthleticClearance.com. There are multiple ways that a document can be scanned and uploaded to the website (printer/scanner, mobile app, etc.). Perhaps the simplest way is to take a picture of it on a phone and upload it. However, documents that are longer than a page may need to be merged into a single file. Here are two great tools that will allow PDFs and JPG images to be merged into one file.
