Abstract:
The Propositional Logic Test (PLT) is a measure of the ability to apply formal statements of logic. It consists of sixteen items, including four each of the conjunction, disjunction, material equivalence and material implication. Reliability of the PLT is high, and it correlates well with a variety of other measures of logical reasoning ability.

Repeated studies indicate that students use only half of the sixteen possible errors on the PLT. Error analysis reveals a developmental pattern in acquisition of conditional reasoning ability.
The PLT is useful for normative assessments, screening students into advanced educational programs, and research into the reasoning process.
