Methodological Advice & Data Analysis Tools
PIAAC's complex study design requires advanced statistical techniques to estimate sampling and measurement variances to analyze the data correctly. The following methodological notes & analysis tools have been developed to support data users in their analysis of the PIAAC data.
PIAAC Data Analysis (Cycle 2)
- The PIAAC Data Analysis Manual serves as a guide for researchers analyzing the microdata of the PIAAC countries that participated in the second cycle of the survey 2022/2023 and complements the Reader's Companion (OECD, 2024) and the Technical Report (OECD, in preparation).

PIAAC User Guide (Cycle 1)
The User Guide (844 kB) contains information about how to link the data of the PIAAC Scientific Use File 2012 to the PIAAC Public Use Files of other countries from Cycle 1 and how to deal with plausible values and the replication weights.
PIAAC Methods Series
The Methods Series Analysis Scripts in Large-Scale Assessments in Education contains selected analysis scripts based on PIAAC data.
In addition, a digital platform - PIAAC scripts digital plattform - is available as an accompaniment to the Methods Series and provides existing analysis scripts (code, syntax) based on previous research with PIAAC data.
