Verb Agreement and Tense Test (VATT)

This is a test of morpho-syntax.

For example the test assesses whether the child adjusts the form of the verb "to jump" depending on who is jumping, e.g. "he jumps" (where it is grammatically correct to add -s to the end of the verb) versus "I jump" (where no -s is added at the end of the verb).

If children do not know how to alter verb endings appropriately, this may signal that they have a language impairment. In particular, children, teenagers and adults with SLI might not adjust the verb endings appropriately, whereas much younger typically developing children will have no problems doing such a task.
