3 Prioritization Criteria for Inclusion

Project datasets are prioritised according to their potential analytical value, comparability with existing data, and contribution to the long-term objectives of the harmonization programme.

When expanding the harmonized pool, projects may be prioritised by:

Recency of data collection
National representativeness
Availability of longitudinal follow-up at the child level
Extended assessment formats (e.g. three-minute oral reading fluency instead of the standard one-minute task)
Inclusion of EGMA modules alongside EGRA
