I teach math, and in my school there are three math tracks. Right now I'm preparing the letters I send home with my recommendations for next year. What is a diplomatic way to tell parents that their kid, who was in a higher track, has not done well enough to stay there? We use a rubric, and I am enclosing their child's results, but I also have to write a personal note, and I'm having trouble saying things like your child didn't do his homework, or worse, you child did his homework but still couldn't pass the tests and never came to get help? Anyone have some good wording?
