Ability and Achievement Tests for Clinical and Educational Use

Ability describes the degree to which a person can carry out certain types of mental operations that generally involve reasoning in some form. Examples include the Test of Memory and Learning (TOMAL-2) and the SON-R Non-verbal Intelligence Tests (SON-R).

Achievement tests are measures of the use and level of development of the use of the ability. Tests such as the Academic Achievement Battery (AAB) can be used across the lifespan.
