This year I developed what I am calling a "Spanish Parent FAQ" to have available as a handout that parents can take with them. I find that many parents want to leave Open House with something tangible because, like us, they are seeing a flurry of people in a condensed period of time. Once the newness of the year wears off and reality sets in, the concerns of parents change, and addressing some of the most common questions up front can save everyone some grief.
During my 15+ years as a Spanish teacher, I have heard the same questions a million times. Parents are all pretty much concerned about the same things because they know that a bad year for their kid equals a bad year for them too. Your focus during face time with parents should always be in communicating that you are dedicated to their child - not just to the standards or the content of your course. They are trusting you with their children, and if you earn their trust in that way, you will have their trust with everything else as well. Use your face time to relate to them on a personal level and let them read about the course "stuff" as they need to.
Here is my FAQ in case you want some ideas for creating your own!
