I have drafted these differentiated KS3 report comments for boys and girls separately. They can be adjusted to your class ability and you only need to change your name.
I produced this power point when I had to train the ITT and NQT teachers on TEFL in mainstream education.
I related this to the Greek Language so as to show to ITTs how difficult it was to understand a language and to enable them to relate to the adaptation to a foreign language.
