(UIS), the regional study centers, IEA, and participating linkage countries. Data collection for the first regional assessment ERCE starts in August 2019 and ends towards in November 2019. All activities related to data processing and data analysis and, eventually the creation of the concordance table will take place throughout the year 2020.

ERCE is a regional Latin American reading and mathematics assessment administered in nineteen Central and South American countries in 2019 and provides a perfect opportunity as a starting point to link the results from a regional assessment to IEA’s TIMSS and PIRLS achievement scales. ERCE measures achievement at the sixth grade. The content of ERCE is expected to align well with the TIMSS fourth grade assessments in mathematics; likewise, the reading component of ERCE is expected to align well with the PIRLS fourth grade assessment in literacy and reading comprehension.

Establishing a link between ERCE and other regional assessments with TIMSS and PIRLS and providing evidence for its precision is regarded as an important strategy to improve reporting towards SDG target 4.1.
