no formal assessment so is it yr 5 yrs old girl can't complete most of the tasks/work assigned by teacher? how is she coping with K1 studies?
Straightaway downgrade 2 levels to nursery is bit weird. Yours 'graduated' from nursery class or didn't attend any... went straight to K1? Maybe change another K1 centre to repeat?
EIPIC is really for kid below 6. Since you knew she needed intervention, why you didn't consider enrolling EIPIC at 3 + nursery classes .... double boast?
