Here are some main points to remember about ADA compliance and website accessibility:
Raw coding -- Don't leave raw coding visible on a page like this https://www.fcps.net/Page/125 or this, email@example.com, because it is awkward for assistive devices and screen-reading software.
Hyperlinks -- Avoid generic verbiage like "Click here." Simply embed the link in the text with words specific to the content.
Also, hyperlinks should be unique on a particular webpage. That is, don't repeat any links unless they point to the same destination.
Example of bad usage: Click this Google form for information about Ms. Smith's class. To follow up with her about the field trip, click this Google form.
Alt text -- Be specific when describing a photo so that you paint a visual picture.
Bad example: file photo of dogs
Good visual: three dalmatian puppies sleeping in a tan wicker basket
Graphics / flyers -- Please use these sparingly. When text is laid over a JPEG image, an assistive device or software cannot "read" the words. It's best to use the image as a billboard promo with very few words, and then link the image to the details you've posted under News & Highlights.
Reminder: Informational flyers are great for sending home in backpacks or posting on hallway bulletin boards, but not so much for websites.
