Make sure to take a second and explain the ins and outs of everything. Yes this takes time, but remember you have been trained to teach kids reading... the parent receiving the info...probably not!
Check out this list from Scholastic about some lingo that you might need to explain some to parents. Your goal is to not intimidate, so you might have a list of words printed so parents can take for some more information. You can break down the words and add definitions in the sentences too. However seems more natural, but make sure you do it! Be very specific. Explain what you need the parent needs to know, don't go into the nuts and bolts unless you really need to.
