For what ages can the VB-MAPP be used?

The VB-MAPP can be helpful for an individual of any age whose language skills are not commensurate with the language skills of a typically developing 4-year-old child. Keep in mind that a typically developing 4-year-old has some very sophisticated language skills. The Barriers Assessment and the Transition Assessment components in the VB-MAPP may reveal problems other than language deficits that can affect individuals of any age, such as prompt dependency, difficulty adapting to change, or when demands weaken their motivation.
