Rosetta Stone is a collaborative project between the UNESCO Institute for Statistics (UIS), IEA, and the TIMSS & PIRLS International Study Centre. The objective of this project is to link together assessments, which have been administered in the recent past, to build concordance tables to compare their outcomes to and benchmark national results to those of the regional assessments. This method enables countries to measure SDG 4 indicator 4.1.1.
