The ATFR assesses an individual’s ability to use the eight formal operational schemata defined by Piaget: Compensations, Correlations, Probability, Combinations, Proportions, Forms of Conservation Beyond Direct Verification, Mechanical Equilibrium and Coordination of Two or More Systems of Reference.
It contains 32 items, organized into eight subtests, assessing one of five levels: Concrete, High Concrete, Transitional, Low Formal and High Formal. Items are presented in a multiple-choice format and responses can be easily hand-scored with a scoring template transparency.
