Linking projects

Projects that are aimed at creating new longitudinal scales at the country level based on IEA studies before and/or after 1995 are published here.

At the moment there are four new achievement scales available for secondary analysis, two in grade 8 mathematics (FIMS 1964 and SIMS 1980) and two in grade 8 science (FISS 1970 and SISS 1984), and all are linked to the current international TIMSS reporting scales.
