Here is a double tool which I used some years ago to validate, in the course of the year, the progressive acquisition of graphemes, classified by sounds.
The first file, modifiable, allows you to validate for every pupil different admitted written forms. It is possible to put a green point, to give up, a date of sure acquisition, in you to choose
Second is a test of reading which can help to fill the first document: reading of graphemes, differentiation of confusions of sounds


To sigtnaler that these tools can be used in link with what is habitually made in class. It would seem to me displaced to fill him there only once, knowing that trainings in reading are progressive.
