A Test Method of Background Questionnaire in Programme for the International Assessment of Adult Competences (PIAAC)

Abstract

PIAAC is new international assessment by OECD, and targeted for adults from 15-year-old to 65. PIAAC assesses Numeracy, Literacy, Problem Solving in Technology- rich Environments, and Background Questionnaires (BQ). BQ is an important position among the survey data in PIAAC. Each participates country does not miss the actual test, for loss of data is not allowed. Therefore test pattern will be reduced with the technique of the combinatorial test; none of all combinations but all pairs of the variables. Applying this method, in the first half there are 30 patterns and the latter half there are 17 patterns, comparatively. The combination inclusion rate between two choices becomes 100%. Time required for the BQ test was to shorten by one person for five hours.
