Writing to Parents

When I discovered that i had to satisfy a PPA standard of establishing a communication with the student's parent-I was a little confused as to how I would be able to do such a thing short of contacting a parent with behavioral issues. Since my CT rarely contacts parents unless there is the utmost necessity, I asked him for some option of how to fulfill this requirement. He made a great suggestion that I should send a letter home with all of my students letting the parents know about who I am and that I will be taking over the class for the next couple of weeks and that this letter is merely informative. I should leave a contact number for me and that I have the capability to update/access grades so parents should feel free to ask me any questions concerning their child. The only question I have is-will this one letter (and any further contacts if parents decide to call during those weeks that I am teaching) fulfill completely that PPA standard?
