I am in the process of writing an information booklet about my class for my new students and their parents. I have a section that talks about absences and what to do if a child will be absent from school. At the end of this section I wanted to write something about vacations during the school year. How can I politely say something that lets parents know that I discourage these types of vacations. This has been a huge problem at our school over the past few years. I don't think that parents realize how much a 2-3 week vacation can affect their child's learning. Any idea on how to word this section?
