Ideally all of the children should now know all of the phonemes (sounds) from each set 1-3 (read write inc)- see the link above to check.
Of course, children all work and learn at a different pace, so do not worry if your child does not yet know them all.
Please continue to carry out daily phonics sessions (10-20 mins is ideal) to learn the sounds that your child has not yet learnt. It is also important to practice reading these sounds within words and to also write them as practice for sounding out unfamiliar words.
Please do email me with any queries.
