The OECD Survey of Adult Skills (PIAAC) assesses the proficiency of adults in key information-processing skills essential for participating in the information-rich economies and societies of the 21st century. These are: literacy, numeracy, and problem solving in technology-rich environments. For more information about the survey have a look at the official OECD website.

During the PIAAC assessement, user interactions were logged automatically. This means that most of the users’ actions within the assessment tool were recorded and stored with time stamps in separate files called log files. The availability of these log files offers new opportunities to researchers, for instance to reproduce test-taking behavior of individuals and to better understand test-taking behavior.
This documentation provides an overview of the interactions being possible in the items and the corresponding logged events.
A selection of possible event types can be displayed where they occur within the items (pop up box) via the Item List and with a technical explanation via the Events sections.

Additional Information about the PIAAC log files

Please note that log files from the cognitive part are not expected to be processed directly. An automatic extraction of variables is made in the [PERSID]-[TESTID]-Var.xml and is released as the Public Use Files (PUFs).
The general structure of each traced event generated by the TAO CBA platform (for details on TAO see chapter 9 of the Technical Report) looks like:
< taoEvent > Name ="origin" Type ="Event Type" Time ="ms"> </ taoEvent >
The attribute "Name" is stating the physical environment from which the event is issued.
There are three possible values: “taoPIAAC”, “stimulus” and “service”. The attribute "Type" helps to classify the traced events in categories; the possible values are covered in the following table, in the “Event Type” column.
The attribute "Time" provides a time stamp expressed in milliseconds; the time stamp is reset to zero (“0”) at the beginning of each unit.
The following tabs present all available event types and include a short description divided by domain.

Event types for Literacy and Numeracy

The PIAAC screen includes a left panel with the directions and sometimes a response area and a right panel presenting the stimulus. Related event types including a short description are presented in the following.

Event types for Problem Solving in Technology Rich Environments

The PIAAC screen includes a left panel with the directions and sometimes a response area and a right panel presenting the stimulus. Related event types including a short desription are presented in the following.

For the events generated in the context of PS, the payload consists of one or several attribute-value pairs.
In case of several pairs, the following separator is used: |*$
