Bit of back story: Y3, teacher new to school, free reading child. School doesn't use any of the reading schemes, they just label different scheme/non scheme books into the usual colour coded system. After they finish, they can just pick whatever book they like, so sometimes DC comes home with really basic books, sometimes with Y6 books. Apart from the odd Luftwaffe type of word, all good.
A few weeks back, we had a meet the teacher afternoon, I went in and had a word with the teacher because DC wasn't sure if who was responsible for changing/prompting the change of the book. Turned out teacher didn't know what level child was at and then confessed she hadn't heard DC read yet. I thought she must be adjusting to the school and the children and just let go. The following week, DC got the teacher's reading assessments all the way from Y2 in the book bag. I wasn't sure if it was meant for me or not so I just left it there. Again, I just thought whoever put it there got a bit mixed up and didn't mention it.
Now, I'm probably the most relaxed, least pushy parent on the planet, but today DC got this as reading book. At first I thought it was just the child being nosy and picking something without the teacher/TA noticing, but someone wrote the title in the reading diary - not child's handwriting. I am as proud of my child as the next parent but even I wouldn't think she should be reading teacher level material. Would it be unreasonable to write a little note in the diary about the appropriateness of this? It's less about the contents of the book and more about the fact that no one seemed bothered about a 7 year old taking a teacher manual home to read.
