National Curriculum reading, is there a definition of 'confidently'.....

[cafco]

I have seen different book bands equate to national curriculum levels, for example 'confidently' reading purple book band equates to a NC level 2C. How perfect does the book need to be read to be assessed as this level? Do they need to be word perfect, expressive, fluent etc or would a child still be reading confidently if they were ready the majority of words correctly? Also my DS (7) often reads the end of the word incorrectly ie, reads jumped instead of jumping or misses off an s from the end of a word. Would this alter how confident he was deemed to be?

there is a whole long list of criteria to match to levels not just reading the words correctly. A 2C would not be awarded for reading 100% correctly if other aspects were missing

Confident means a range of skills from being able to read fluently to being able to demonstrate understanding of the text, with some degree of interpretation; tackling new words with confidence and using learned techniques to do so; not paraphrasing or skipping words if reading fast.
