Data file: PIRLS 2006 - Population 1 - Student Achievement File - All Countries v1.0
The student achievement data file contains the student responses to the individual achievement items in the PIRLS reading test. The student achievement data file is best suited for performing item-level analyses. Achievement scores (plausible values) for each of the PIRLS 2006 reading scales are available in the student achievement data file, as well as in the background questionnaire data file. Thus, it is usually not necessary to link these two data file types.
Students who participated in PIRLS were administered one of 13 test booklets, each with a series of questions. Some of these questions were multiple-choice items and some were constructed-response items. The student achievement data files contain the actual responses to the multiple-choice questions and the scores assigned to the constructed-response items.
