Can the forms be used for anges below 1.5 and above 5?

Answer: For children who are a few months younger than 1.5 or older than 5, there is not likely to be much error in using the forms and their norms.  However, the greater the deviation in age from the norms, the less appropriate they will be.  If children are to be reassessed over periods that are mainly within the 1.5-5 year range but include one or two assessments that are no more than about 4 months outside this range, it may be better to use the preschool forms at all assessments points to maintain complete continuity of item and scale scores, rather than using other instruments.
