It is good before you embark on some form of remediation, to conduct a baseline assessment so that you can quantify what progress, if any has taken place.
This is not only for noting the pupil’s progress but also the effectiveness (or lack of) of the intervention that has been used.
If after a couple of months no progress is seen, then it may be worth trying a different intervention or evaluating the elements that are in the intervention and the training of the adult and mindset of the child. It is also worth considering the working relationship between the child and adult and if a change of personnel would be useful.
