Every year I would get my KS1 classes to do 2 or 3 talks. The first was usually about themselves, the second on a topic related non-fiction subject e.g. an animal and if I did a 3rd it varied in focus from poetry to a favourite toy to explain something they had made etc. I completed this using peer observation and or teacher observation. As I kept these pasted in their literacy books (alongside a picture of them in their talk) it was useful to see progress and helped me with evidence when writing reports. Often I would send a copy home for parents too as immediate feedback, I especially found it useful when I found myself out of class so that observations were consistent by whoever covered me.
